[PATCH util/modular] release.sh: adjust for changed git status exit codes.

[Peter Hutterer]

git status in git-1.7 always returns 0, regardless of the number of
uncommitted changes. Replace this with a script to parse through the git
status output (ignoring uncommitted files).

[commit 9e4b7ab652561e1807702fe5288e04b8873fc437
 git status: not "commit --dry-run" anymore
 in the git source tree]
