modutils: remove special handling of uClibc
Commit 3a45b87ac36f (modutils: support finit_module syscall) introduced
macro finit_module. But it is not defined for uClibc.
The compilation for busybox fails for MIPS with:
With uClibc, we get following build errors:
modutils/lib.a(modutils.o): In function `bb_init_module':
modutils.c:(.text.bb_init_module+0x94): undefined reference to `finit_module'
modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module'
We can just use syscall() without any need for the
uClibc wrappers.
Newer versions of uClibc-ng (>1.0.20) will remove the
module syscall wrappers.
