clang build script: Clobber old Android toolchains.

https://codereview.chromium.org/2317123004 switched the Android bits of
the script to the new .py script.  That script needs an explicit --force
flag to clobber old Android toolchains, else it errors out with

  Running make_standalone_toolchain.py --api=21 --install-dir=... --stl=stlport --arch=arm64
  Installation directory already exists. Use --force.
  Failed.

if the --install-dir already exists (for example, from a previous build).
