lib: system() is bad, use libkmod instead

For an as of yet unknown reason, calling system("modprobe") from inside
igt/gem_wait causes kasan to spend 1-5 minutes copying the process
pagetables. This evaporates if we replace the fork-happy call to system
with a call to load the module using libkmod. So be it.
