systemd: backport patch to fix build when gcrypt is enabled

When gcrypt support is present in PACKAGECONFIG, build fails due to the bug
reported in [1]. Since this is already solved upstream, this commit backports
the corresponding patch.

+"noreturn" is reserved and can be used in other header files we include:

+  [   16s]  void gpgrt_log_bug (const char *fmt, ...)    GPGRT_ATTR_NR_PRINTF(1,2);
