[Buildroot] [PATCH v2,1/1] package/systemd: fix build with -Ofast

[Fabrice Fontaine]

Update -Ofast workaround as suggested by Yann E. Morin to avoid the
following build failure raised since bump to version 252.4 in commit
a2c823d1f548d5a0120d27d6c000603192360f7b and
https://github.com/systemd/systemd/commit/60f97fee2d2f948c8e8963ea8ff767008cb93cae:

../output-1/build/systemd-252.4/meson.build:397:8: ERROR: Problem encountered: -Ofast, -ffast-math, or -ffinite-math-only is specified in c_args.

Fixes:
