[OE-core] [PATCH 1/1] systemd: avoid musl specific patches affect glibc systems

[Chen Qi]

systemd upstream only care about glibc. We made musl specific
patches so that systemd could work. But currently these patches
contain potential security issues.

So apply these patches only when the libc is musl.
