This is a follow up to #200815 and #184634.
The PCRE2 JIT SEAlloc does not support the `fork()` as announced in
their README [0]:
> If you are enabling JIT under SELinux environment you may also want to add
> --enable-jit-sealloc, which enables the use of an executable memory allocator
> that is compatible with SELinux. Warning: this allocator is experimental!
> It does not support fork() operation and may crash when no disk space is
> available. This option has no effect if JIT is disabled.
As a result using it in PHP can break apps and tools, it can only be
enabled under very specific context where you have a full picture of
what the PHP code is doing.
This contribution disables again the PCRE2 JIT SEAlloc and extends the
existing PHP/PCRE2 tests to make sure we do not enable it again by
mistake.

Currently paths are handled by `types.package`, whose semantics are a
bit of a mess. In particular, it converts path values to derivations
using `toDerivation`, which will lead to problems when flake `outPath`s
become paths in https://github.com/NixOS/nix/pull/6530.
This change makes the "incompatible changes" section in the above PR
obsolete: `nix.registry.nixpkgs.flake = nixpkgs;` works as expected (the
flake is copied to the store).
Hided home/trash/network desktop icons by default.
Also changed their default logo settings (cs_info and menu), so what we
should modify to cinnamon-symbolic is now linuxmint-logo-ring-symbolic.
We are lucky, linuxmint-logo-ring-symbolic only appears in a few other
places and non of them are useful, menu@cinnamon.org/settings-override.json
simply won't work because cinnamon-common doesn't know that file.
Also set default cursor theme, this package now directly provides those
cursor themes. And, we now default to the Mint-Y-Aqua theme.
