[RFC PATCH] modutils: fix build with uClibc

[Rahul Bedarkar]

Commit 3a45b87ac36f (modutils: support finit_module syscall) introduced
macro finit_module. But it is not defined for uClibc.

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'

This commit guards usage of finit_module when not using uClibc.

This build issue is detected by Buildroot autobuilder:
