Revert of untrusted.gyp to fix goma_status=ok error.

Revert r12387: "Enables goma from GYP and GOMA_DIR env."

Since r12387 caused following error, let me revert r12387:
Updating projects from gyp files...
gyp: name 'goma_status' is not defined while evaluating condition
'goma_status!="ok"' in
/mnt/scratch0/b_used/build/slave/linux/build/src/components/nacl.gyp

It would be cleaner to revert all of r12387 rather than just part of it. 
Presumably the parts you're currently not reverting are not useful on their own?

Also, let me send change for build_nexe.py later because I would like to provide
the way to disable burst compile request even if goma is available.
