floxify package build (#5)

* de-flakify

* floxify

* flakebump

* fix: add version to package metadata and profile package names

* etc-profiles: updated description

* output refactoring

- include base in list of outputs
- split 0100_common-paths.sh into a separate output

* refactor: don't link base etc/profile from profile outputs

* rename ld-rheload -> ld-floxlib

Updated ld-rheload to fall back to $FLOX_LIB (instead of the RHEL
default /lib64) and renamed package accordingly.

* flakebump

* Update for Mac

The Darwin linker has the DYLD_FALLBACK_LIBRARY_PATH variable which
accomplishes more or less the same thing we do on Linux using LD_AUDIT
and ld-floxlib, by allowing us to append a "last chance" location for
finding shared libraries when all else fails.

* empty commit to bump version number

* Update trivial-test.yml (#6)

* Update compare-nix.yml (#7)

* Update compare-nix.yml

* Update compare-nix.yml
