bug#40977: --load-path does not honor ~

[Hartmut Goebel <h.goebel@crazy-compilers.com>]

Hi,

This is not related to #40549.

The short option "-L ~/…" works, since thin this case the shell resolves the tilde. Whereas for the long-option the shell does not revolve the tilde, since the tilde is in the middle of the argument. Yu can verify this yourself easily:

$ python -c 'import sys; print(sys.argv)' ~
['-c', '/home/hartmut']
$ python -c 'import sys; print(sys.argv)' -L ~
['-c', '-L', '/home/hartmut']
$ python -c 'import sys; print(sys.argv)' ---long=~
['-c', '---long=~']


Proposed solution:

After processing options, guix need to "expanduser()" (as it is called
in Python) on all arguments which are paths.
