biber: add patch to fix biber on perl 5.36
With perl 5.36, biber now fails with a syntax error:

This patch was taken directly from biber upstream: https://github.com/plk/biber/commit/d9e961710074d266ad6bdf395c98868d91952088 . A clean fix would be updating biber, but as biber is released in lockstep with biblatex (and has strict version requirements going both ways), updating the TeXLive packages isn't really something I'm able to do.

Without this patch, invoking biber at all results in the following crash:

```
$ biber --help
Can't modify undef operator in scalar assignment at /usr/share/perl5/vendor_perl/Biber/Section.pm line 373, near "undef;"
Compilation failed in require at /usr/share/perl5/vendor_perl/Biber.pm line 24.
BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/Biber.pm line 24.
Compilation failed in require at /bin/biber line 17.
BEGIN failed--compilation aborted at /bin/biber line 17.
```

#### Testing the changes
- I tested the changes in this PR: **YES**

#### Local build testing
- [x] I built this PR locally for my native architecture, x86_64-glib
- I did **not** build this PR locally for other architectures, as biber is written in perl and the change is relatively minor.
