Add feature to check for free disk space early at genkernel start
To avoid preventable errors like running out of disk space while building
a new kernel, two new options, --check-free-disk-space-bootdir and
--check-free-disk-space-kerneloutputdir, were added.
When set, disabled by default, genkernel will check early before
starting to build kernel/initramfs for specified amount of free
disk space.
