Fixes <https://issues.guix.gnu.org/58861>.
Previously the order of the options giving to 'guix shell' could mean that the
'glibc-for-fhs' package included with the '--emulate-fhs' option would not
appear in the container. For example, using the development option with a
package using the 'gnu-build-system', e.g. 'guix shell -CFD hello', would
include the regular 'glibc' package. The option ordered mattered: 'guix shell
-CD hello -F' would include the expected 'glibc-for-fhs'. We fix this by
having 'glibc-for-fhs' added to the package list just before calling
'options-with-caching' so the option order given by the user does not matter.
* guix/scripts/shell.scm (%options): Move the '--emulate-fhs' (expression
. ...) component from here...
(parse-args): ... to here.
* tests/guix-environment-container.sh: Add a test to check that
'glibc-for-fhs' is in the container even when 'glibc' is included in the 'guix
shell' package list.
