chore(CI): Handle build scripts called with relative paths with spaces

foo=dirname "$0" only works if the script is called with an absolute path and
that path contains no spaces. Add quotes everywhere to contain spaces in
directory names or file names, and add realpath to get the absolute path
regardless of call path.

Not necessarily needed, but like in e405868037
it can avoid some annoying issues when e.g. that script was called with a
relative path in CI.
