util-linux: one package per binary (pt 3: sbindir)

util-linux: one package per binary (pt 3: sbindir)

Similar to the previous patch.

Existing packages (and current dependency by main package):
* blkdiscard <- RRECOMMENDS
* findfs
* fsck.cramfs
* mkfs <- RRECOMMENDS
* mkfs.cramfs
* partx
* readprofile <- RRECOMMENDS
* rfkill
* runuser <- RDEPENDS
* sfdisk <- RRECOMMENDS
* uuidd

New packages:
* too many to list

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.

Nevertheless, all existing packages have been added to
RRECOMMENDS this time, even if they weren't in RDEPENDS /
RRECOMMENDS before.
