Add //google_apis/* to 'gn check'.

Add //google_apis/* to 'gn check'.

This fixed the remaining erros found by 'gn check', so we can enable it
on all bots.

Checked with the following command lines:

Linux
$ gn gen out-gn
$ gn check out-gn //google_apis/*

$ Android
$ gn gen out-gn-android --args='target_os="android"'
$ gn check out-android //google_apis/*

$ ChromeOS
$ gn gen out-gn-chromeos --args='host_os="chromeos"'
$ gn check out-gn-chromeos //google_apis/*

BUG=None
TEST=see above

lgtm. 

Make sure you specify

CQ_EXTRA_TRYBOTS=tryserver.chromium.linux:android_chromium_gn_compile_dbg,android_chromium_gn_compile_rel;tryserver.chromium.win:win8_chromium_gn_rel,win8_chromium_gn_dbg;tryserver.chromium.mac:mac_chromium_gn_rel,mac_chromium_gn_dbg

in the CL description so that the CQ will test all of the GN bots that aren't
part of the default set.
