The TL(custom-v8) task started to often hit the task's run limit of 1h this week.

There is one task which still ran in 12 minutes like the older ones, newer ones are close to an hour or hit the limit.

This successful but long running task has two "hangs":

This patch attempts to fix the long-running customv8 toolchain tasks by adding a --force to the fetch v8 call. This additional option prevents fetch from checking for existing .gclient files (which should never exist) to help with the long delay we are seeing in this call.
