writers.makeScriptWriter: fix on Darwin\MacOS (#93757)
* writers.makeScriptWriter: fix on Darwin\MacOS

On Darwin a script cannot be used as an interpreter in a shebang line, which
causes scripts produced with makeScriptWriter (and its derivatives) to fail at
run time if the used interpreter was wrapped with makeWrapper (as in the case
of python3.withPackages).

This commit fixes the problem by detecting if the interpreter is a script
and prepending its shebang to the final interpreter line.

For example if used interpreter is;
```
/nix/store/ynwv137n2650qy39swcflxbcygk5jwv1-python3-3.8.3-env/bin/python
```

which is a script with following shebang:
```
#! /nix/store/knd85yc7iwli8344ghav3zli8d9gril0-bash-4.4-p23/bin/bash -e
```

then the shebang line in the produced script will be
```
#! /nix/store/knd85yc7iwli8344ghav3zli8d9gril0-bash-4.4-p23/bin/bash -e /nix/store/ynwv137n2650qy39swcflxbcygk5jwv1-python3-3.8.3-env/bin/python
```

This works on Darwin since there does not seem to be a limit to the length
of the shabang line and the shebang lines support multiple arguments to
the interpreters (as opposed to linux where the kernel imposes a strict limit
on shebang lengh and everything following the interpreter is passed to it
as a single string).

fixes; #93609
related to: #65351 #11133 (and probably a bunch of others)

NOTE: scripts produced on platforms other than Darwin will remain unmodified
by this PR. However it might worth considering extending this fix to BSD systems
in general. I didn't do it since I have no way of testing it on systems other
than MacOS and linux.

76437a88bb writers.writePython2 and writePython3: use "bare" python if no deps are needed
`python.withPackages` has a runtime dependecy on bash since it's wrapped with
`makeWrapper`. This fix avoids bash as runtime dependency when it's not
needed.

493c357720 pkgs/build-support/writers: use runCommandLocal for scripts
If we just want to write a non-compiled script (e.g. writeDash), it’s
usually a lot faster just doing it locally. That’s what
`runCommandLocal` was introduced for, so let’s use it in `writers`.
