Switch the default `git try` / `gcl try` bots to _rel.
That matches the CQ bots, and they're significantly faster.
The global trybots are added to all subdirectory PRESUBMITs automatically, so remove win, linux, mac from subdirectory PRESUBMITs (instead of changing them too).
BUG=99521
TEST=`git try` creates faster tryjobs.
