systemd: Correctly check ENABLE_GSHADOW with if/endif
Use commit
4f07ffa8f5ab ("Use #if instead of #ifdef for ENABLE_GSHADOW")
from upstream to check ENABLE_GSHADOW correctly that is defined as 0
in case of musl.
While there replace specific patch with one from upstream that does
exactly the same commit
66a5b5ce9b99 ("basic/user-util: properly protect
use of gshadow").
