[PATCH v2 11/15] util-linux: one package per binary (pt 4: bindir)

["André Draszik" <git@andred.net>]

From: André Draszik <andre.draszik@jci.com>

Similar to the previous patch.

Existing packages (and current dependency by main package):
* ionice <- RRECOMMENDS
* lsblk <- RDEPENDS
* lscpu
* mcookie
* prlimit <- RRECOMMENDS
* unshare
* uuidgen

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.

Unfortunately, we need to add explicit ALTERNATIVE_LINK_NAME[]
for a few cases, as previously they were implied using
defaults by being specified in ALTERNATIVE_${PN}. We can't
easily automate that using do_split_packages(), so we
simply add them explicitly.

[YOCTO #13058]

v2: * Fix handling of escape characters in regexs and hence fix python
      Deprecation warnings which will be problematic in python 3.8.
    * use PN for package name prefix, not BPN
