git.sh: allow patching submodules

for single-tree project (e.g. flashprog):
config/submodule/PROJECT/MODNAME/patches

for multi-tree project (e.g. coreboot):
config/submodule/PROJECT/TREE/MODNAME/patches

MODNAME is e.g.:
3rdparty/vboot directory in coreboot: would become vboot
(the submodule codepath is filtered to up to the final slash)

another example:
submodire src dir 3rdparty/foo/bar
MODNAME would be "bar"

Add whatever patches you like to a given submodule.

An example patch is included in this commit.
