Christoph Reiter 4d3783d0d9 python-installer: don't use "<launcher_dir>" with normal scripts (#26601)
installer not only generates launcher scripts, it also rewrites shebangs
for old-style setuptools scripts. In that case we need to write a real
shebang and not just one which simple_launcher understands.

Instead of patching the source interpreter path, derive the relocatable
shebang from it in both places.
