v2.3.2 — RAM-mode /boot space preflight check

dracut -f writes the rebuilt initramfs to a .tmp file next to the
existing one for that kernel before renaming over it, so /boot briefly
needs room for both at once, not just the new image. A user (hd3291)
hit a raw "No space left on device" from zstd on a /boot that looked
like it had enough headroom (kernel-rt install keeps the previous
kernel, and DNF retains multiple versions by default).

Module 13 now checks free /boot space against the current initramfs
size before every dracut -f call (overlay enable and disable paths)
and fails with an actionable message — free up a kernel, or use
Strategy V (volatile), which needs no dracut rebuild at all.
