[Buildroot] [git commit] lcdproc: use ac_cv_mtab_file

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=b4501ca80d9c02984e5d0715b999d8d638cda544
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Set ac_cv_mtab_file to /etc/mtab otherwise build will fail if no mtab,
mnttab or fstab is found in /etc (on host)

Fixes:
