android webview build: Stop using envsetup.

By now, envsetup only sets OS=android and converts GOMA_DIR to the corresponding
gyp defines. It also sets GYP_CROSSCOMPILE. Nothing but the OS=android bit is
used by the webview build, so let android_webview/tools/gyp_webview set what
it needs directly instead of going through envsetup.

(envsetup also does a few envvar chanes to PATH etc, but gyp_webview calls
envsetup in a subshell, so it doesn't see these changes anyways.)

As a side effect, android_webview/tools/gyp_webview no longer ignores
GYP_DEFINES from the environment.
