(pkgsStatic.perl): Patch Perl to avoid duplicate symbols with musl.

This commit backports a commit introduced on Perl 5.39.2 to allow
`pkgs.pkgsStatic.perl` to compile without raising errors about duplicate
symbols being defined during the linking process.

This fixes NixOS#295608

| Tested on | Status |
| --- | --- |
| M1 Mac (aarch64-darwin) | Failed due to other issues* |
| NixOS VM (x86_64-linux) | Compiled |
| Nix (aarch64-linux) | Compiled |

**Test method**:

```sh
nix repl -I nixpkgs=$PWD
nix repl> pkgs = import <nixpkgs> {}
nix repl> :b pkgs.perl
nix repl> :b pkgs.pkgsStatic.perl
```

Despite the upstream commit being scoped to all environments, we are only
applying this patch only on the `pkgsStatic` context to avoid rebuilding all of
NixOS packages by changing Perl.

It includes an additional build flag [also used upstream](Perl/perl5#22052)
for configuring static builds.

*MacOS: `pkgsStatic.perl` still fails to compile after this change due to MacOS
case-insensitiviness affecting the build recipe under /tmp, as
`perl-cross/configure` is copied over `perl/Configure` file, as well as not
finding `readelf` for the `configurePhase`.
