[gentoo-dev] [PATCH] check-reqs.eclass: more disk checks

["Robin H. Johnson" <robbat2@gentoo.org>]

Allow checking more disk space, for users with many split volumes and
ever-larger packages.

gentoo-kernel-bin:
/     >=350MB/version (in /lib/modules)
/boot >=40MB/version

rust-bin:
/opt  >=450MB/version
