Subject: [PATCH 141/217] build: Automate rpmbuild.sh

Prior to the meson conversion rpmbuild.sh with no arguments would find a
pre-created ndctl.spec file relative to the script. Restore that
behavior by looking for the script in the build/ directory, and try to
create it if not there.

Yes, this fails if someone picks a directory other than build/ for the
output directory, but build/ is conventional.

Another regression from autotools is the loss of support for building
"dirty" rpms i.e. rpms from git source trees with uncommitted changes.
At least provide a coherent error message for that case.
