podman: add rdepend on nsenter

Podman requires nsenter (for obvious reasons) .. and while this
dependency is normally satisfied on images (via busybox), it is
possible to build a minimal container image that excludes
busybox .. and hence will not have nsenter present.

Rather than making this a hard rdepends on util-linux-nsenter,
we use a variable: VIRTUAL-RUNTIME_base-utils-nsenter, which
can either be set to busybox or util-linux-nsenter (the current
default).

The VIRTUAL-RUNTIME_base-utils- format follows similarly named
OEcore providers and variables .. which the exception that there
is no entry in the preferred providers file there, and there's
no package created called busybox-nsenter (but perhaps there
could be in the future).
