submodule: correctly delimit the keys to use for lookup

carlosmn · carlosmn · commit e0af3cb30c10 · 2015-07-01T21:15:06.000+02:00
The regex we use to look at the gitmodules file does not correctly
delimit the name of submodule which we want to look up and puts '.*'
straight after the name, maching on any submodule which has the seeked
submodule as a prefix of its name.

Add the missing '\.' in the regex so we want a full stop to exist both
before and after the submodule name.
