subcmds/sync: Disable autoDetach for git gc.

gc.autoDetach is enabled by default which makes 'git gc --auto' return
immediately and run in background. This can lead to a pile up of
operations all using large amounts of memory at the same time. To avoid
this set gc.autoDetach to false so that the garbage collect task waits
for instances to finish before spawning more.

Bug: https://crbug.com/gerrit/15113
Test: repo sync -j # and check the number of 'git gc' processes
