Revert "missing: Don't call syscall() with syscallno == -1"

This reverts commit 38829712e5c411bc250aeae142fc6bf06e794d58.  It fixes
the problem, but it breaks the testsuite for those who don't have
__NR_finit_module. The testsuite would have to make the same check.

Instead, I'm reverting this change and I'm going to apply another patch
from Jan Luebbe who got this right from the beginning.
