The wrong data in modules.builtin.modinfo can cause overflow or
double free from modinfo with libkmod-builtin. Fix the error
cases with strict checking.

Seung-Woo Kim (2):
  libkmod: fix an overflow with wrong modules.builtin.modinfo
  libkmod: fix possible double free with wrong modules.builtin.modinfo
