On Tumbleweed we have glibc 2.38 already thus string functions
like strlcpy will be present and won't be needed from libbsd.
`readpassphrase()` is then the only function from libbsd not present.
Upstream shadow has an in tree copy of it, that is used when the
`--without-libbsd` flag is passed along.
By relying on glibc 2.38 we don't need to add libbsd and libmd
to our ring0 but can't easily upgrade on SLE.
