Subject: [PATCH 04/63] [release-branch.go1.5] build: Fix bootstrap.bash for
 official source tarballs

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.

Fixes #12223
