Subject: build/f_repos: Allow out-of-tree .git dir
X-Git-Tag: danube.1.RC1~103

build/f_repos: Allow out-of-tree .git dir

ArmbandFuel@OPNFV uses Fuel@OPNFV git repo as a submodule, so
its .git dir is located outside work tree root (F_GIT_ROOT).

Allow this setup by parsing `git rev-parse --git-dir` intead of
harcoding git dir path.

Fixes: FUEL-200
