Subject: [PATCH] libkmod: fix possible double free with wrong
 modules.builtin.modinfo

Conflict:NA
Reference:https://git.kernel.org/pub/scm/utils/kernel/kmod/kmod.git/commit/?id=675410c3b3b1cf4523f02ab6e3128c39bd5d5101

Fix double free for *modinfo with non '\0' terminated wrong
modules.builtin.modinfo, which is because EOF is minus value.
