build: Fix bootstrap.bash for official source tarballs

fawick · adg · commit 1ac84d4300a1 · 2015-09-01T19:52:59.000Z
At the moment, bootstrap.bash assumes it is called from a git working copy. Hence, it fails to complete when running in an unpacked official source tarball where .git and .gitignore do not exist. This fix adds a test for existence for .git and a -f switch for the removal of .gitignore.
