linuxPackages_latest.perf: add `-O1` workaround for `gcc-13`
Without the change `perf top` just crashes early as:
$ perf top
perf: Segmentation fault

It's a known `gcc-12+` bug not yet fixed in `gcc-13`: https://gcc.gnu.org/PR111009
Let's demote optimizations from `-O2` down to `-O1` to disable any
VRP-related effects for affected `gcc-13`.
