ci/mkosi: enable sanitizers on Fedora 41

It seems the recent update of LLVM package in Fedora rawhide breaks
sanitizers, and udevd freezes after false-positive (I guess) issue is
detected:

systemd-udevd[2646]: =================================================================
systemd-udevd[2646]: ==2646==ERROR: AddressSanitizer: stack-buffer-underflow on address 0x7ffc3a642660 at pc 0x555627ac022b bp 0x7ffc3a6422b0 sp 0x7ffc3a6422a8
systemd-udevd[2646]: READ of size 8 at 0x7ffc3a642660 thread T0 ((udev-worker))

llvm-19.1.7-11.fc43 worked fine, but llvm-20.1.0-1.fc43 does not.
To avoid the issue, let's enable sanitizer on Fedora 41, and disable it
on Fedora rawhide.

Closes #36678.
