Revert of Add support for escaped target names in isolate driver (3rd try)

Revert of Add support for escaped target names in isolate driver (3rd try) (patchset #2 id:20001 of https://codereview.chromium.org/1130523003/)

Reason for revert:
Looks like interactive_ui_tests needs a dep on chrome too:

http://build.chromium.org/p/chromium.chrome/builders/Google%20Chrome%20Linux/builds/40889/steps/compile/logs/stdio

FAILED: cd ../../chrome; python ../tools/isolate_driver.py check --isolated "../out/Release/interactive_ui_tests.isolated" --isolate "interactive_ui_tests.isolate" --path-variable DEPTH .. --path-variable PRODUCT_DIR "../out/Release " --extra-variable "version_full=44.0.2398.0" --config-variable "CONFIGURATION_NAME=Release" --config-variable "OS=linux" --config-variable "asan=0" --config-variable "branding=Chrome" --config-variable "chromeos=0" --config-variable "component=static_library" --config-variable "disable_nacl=0" --config-variable "enable_pepper_cdms=1" --config-variable "enable_plugins=1" --config-variable "fastbuild=0" --config-variable "icu_use_data_file_flag=1" --config-variable "internal_gles2_conform_tests=0" --config-variable "kasko=0" --config-variable "libpeer_target_type=static_library" --config-variable "lsan=0" --config-variable "msan=0" --config-variable "target_arch=ia32" --config-variable "tsan=0" --config-variable "use_custom_libcxx=0" --config-variable "use_instrumented_libraries=0" --config-variable "use_prebuilt_instrumented_libraries=0" --config-variable "use_openssl=0" --config-variable "use_ozone=0" --config-variable "use_x11=1" --config-variable "v8_use_external_startup_data=1"
Failed to find an input file: Input file /b/build/slave/google-chrome-rel-linux/build/src/out/Release/chrome doesn't exist

Reverting for now, but should be easy to fix.

Original issue's description:
> Add support for escaped target names in isolate driver (3rd try)
>
> Currently the isolate_driver.py which creates the dependency files
> used by the isolate system, does a simple split on all spaces when
> trying to identify targets.
>
> This can fail if the target name contains a space in the name. In
> ninja, spaces are escaped with a $-prefix. An example would be
> 'Content$ Shell$ Helper.app'.
>
> This CL adds support for such target names and ensures that they
> stay as one item. Doing this uncovered a few missing dependencies
> and a missing file in some .isolate-files for the component build
> on Mac.
