Revert build/common.gypi modified in r140431.

The change caused issues when running make with goma because the envirnoment
variable CXX_target etc. set in build/android/envsetup.sh are not full paths.
Should check with yfriedman@ why full paths are needed for ninja.

Revert build/common.gypi before the change.

build/android/envsetup.sh of r140431 is good.
