subrepo: fix subrelpath for git subrepos

This patch conforms gitsubrepo code to the variable naming scheme of the other
subrepo implementations. All user-facing path references should be relative
to the root repository.

from hgext import color

# ensure errors aren't buffered
testui = color.colorui()
testui.pushbuffer()
testui.write('buffered\n')
testui.warn('warning\n')
testui.write_err('error\n')
print repr(testui.popbuffer())
