linuxManualConfig: patch all shebangs in scripts/

There are many scripts in `scripts/` which may be called by the build,
depending on how the user chooses to configure the kernel. For example,
`scripts/jobserver-exec` is called whenever the kernel is being built
with LLVM tooling, and without this patch that build will fail due to
the broken shebang.

This patch makes us fix _all_ scripts, as well as add a dependency on
python3Minimal, since a lot of the aforementioned scripts are written in
Python3 instead of shell.
