bash-completion: fix runuser install

The runuser symlink used to depend on su being enabled, but a refactoring
broke that.  So if you build with runuser enabled but not su, you end up
with a broken symlink.  Rework the logic so it works in both cases.

fstrim: initialize path variable

Reading the code this initialization is not necessary, so the change is
mostly about silencing a compiler warning and ensuring the program keeps
on working if there is a future bug that could make uninitialized 'path'
reachable to use.

function

bash-completion: stop being clever when listing block devices

Various commands such as blkid, cfdisk, fdisk, delpart, and so on listed
only partitions and missed for example disks and volume groups.  The
right thing to do is to list all block devices in all for all commands
performing operations with them.  This might occasionally list unexpected
devices that I think is lesser bad than missing some.

libmount: improve kernel command line parsing

The current command line parser will stop at the first occurrence of an
option, however the kernel does the opposite.  So if you have:
	root=/dev/sda1 root=/dev/sda2
When you look for "root", the kernel will use /dev/sda2, but util-linux
uses /dev/sda1.

Further, if args are passed to custom init programs, the parser will
pick those up as kernel options.  So if you have:
	root=/dev/sda1 -- /foo bar=yes
The kernel will stop at the "--" and pass the rest to userland.  But if
you look for "bar", util-linux will incorrectly return "yes".

Ultimately, there's no way for util-linux to exactly parse the command
line the same way as the kernel -- we don't know exactly which ones the
kernel picks up and which it passes on to userland (either as env vars
or as command line args).  The kernel passes all unrecognized options.
These updates are simple best effort.

hexdump: use 'll' format modifier instead of the non-standard 'q'.

The printf(3) man page says about 'q':
("quad". 4.4BSD and Linux libc5 only. Don't use.) This is a synonym for ll.

This fixes hexdump with musl libc.
