Although we try finit_module() on compressed modules to let the kernel
determine if it's an ELF

Treat the kernel better by just doing a very basic ELF header check
before calling finit_module().

Changelog:
v2:
- Fix the unreleased fd in the modutils.c
- Add extra #ifdef to avoid compiling the check if finit_module() is no
avaiable
- Add the 2nd patch to handle modprobe-small
