Subject: meson: also disable -Wmaybe-uninitialized when -Ofast is specified
X-Git-Tag: v258-rc1~456^2

meson: also disable -Wmaybe-uninitialized when -Ofast is specified

At least with GCC-14, -Ofast produces many false-positive warnings.
```
$ gcc --version
gcc (GCC) 14.2.1 20250110 (Red Hat 14.2.1-7)
```
