util-linux: one package per binary (pt 2: base_bindir)

util-linux: one package per binary (pt 2: base_bindir)

Similar to the previous patch.

Existing packages (and current dependency by main package):
* mount <- RRECOMMENDS
* umount <- RDEPENDS
* mountpoint <- RRECOMMENDS
* getopt
* su <- RDEPENDS

New packages:
* dmesg
* kill
* more

To avoid breaking existing users, all the new packages
are added to the main package as RRECOMMENDS_${PN}, so
they are pulled into existing images etc.

The existing RDEPENDS_${PN} will need some further
clean-up in the future, as it appears a bit random which
packages the main package depends on vs. recommends.
Existing packages that aren't in RDEPENDS / RRECOMMENDS
haven't been added to RRECOMMENDS for that reason.
