gexp: Make 'local-file' follow symlinks.
Fix <https://lists.gnu.org/archive/html/guix-devel/2024-08/msg00047.html> via making 'current-source-directory' always follow symlinks. * guix/utils.scm (absolute-dirname, current-source-directory): Make them follow symlinks. * tests/gexp.scm ("local-file, load through symlink"): New test. Fixes: guix/guix#3523 Change-Id: Ieb30101275deb56b7436df444f9bc21d240fba59 Signed-off-by: Florian Pelz <pelzflorian@pelzflorian.de>
