Disable bundled_binutils and bundled_gold on Linux

Keep bundled binutil scripts but not downloading actual binaries by default.

Automatic downloading of binutils has been causing problems for some users:
see #164, #412, #440.

Using bundled binutils helps reduce linking time, but packager codebase is
relatively small, so the gain is not significant.

Local testing shows that the full build time increases from 1m42s to 1m50s, i.e.
an increase of about 8s, or ~8%.

User can still enable the usage of bundled binutils by running
'python src/packager/third_party/binutils/download.py' and set
'linux_use_bundled_binutils' and 'linux_use_bundled_gold' to 1 in GYP_DEFINES.
