package/kvmtool: fix a musl build issue on ARM

We simply bump the version rather than backport the patch, as there has
been only very few, minor commits in-between.

The kvmtool build with musl still produce some warning but they are
fixed with the current master 0093df80 (kvmtool: Makefile: disable PIE
build for bios and pre_init). So the next version bump should fixes
them.
