gexp: Preserve source location for #~ and #$ read extensions.
Read hash extensions preserve source location info as source properties
on their result. However, in Guile 3.0.8, that location would be
dismissed, leading 'local-file' to fail to resolve file names relative
to the source directory.
Fixes <https://issues.guix.gnu.org/54003>.
Reported by Aleksandr Vityazev <avityazev@posteo.org>.
* guix/gexp.scm <eval-when> [read-syntax-redefined?, read-procedure]
[read-syntax*]: New variables.
[read-ungexp]: Adjust to expect either sexps or syntax objects.
[read-gexp]: Call 'read-procedure'.
* tests/gexp.scm ("local-file, relative file name, within gexp")
("local-file, relative file name, within gexp, compiled"): New tests.
