Added the -L --line option to free to show a small
set of memory statistics on a single line of 80 characters.
Largely based on the work of @Ulenrich1 and updated to
the new API.

E.g. on my system I see this output to "free -vh", which fails the test:
total used free shared buff/cache available
Mem: 23Gi 17Gi 311Mi 2.2Gi 8.1Gi 5.8Gi
Swap: 2.0Gi 1.9Gi 105Mi
Comm: 13Gi 44Gi -31Gi
The previous two patches updated free, but needed a tweak and the tests
also needed to be updated. I've hand-calculated the results using bc and
both the testsuite and bc results equal what free prints out.

Free always used 1024 based units but used the confusing old style
kilo,mega etc.
This change changes the names to kibi,mebi for 1024 based divisors
and kilo,mega for 1000 based divisors or IEC units.
It also checks if you try to set two units, e.g free -k -m
Petabyte and Pebibyte have been added.
If you used to use the long options such as --mega these will now
actually print megabytes (they previously printed mebibytes).
The short options are being used on the IEC units

free got a makeover to suit the newer kernel memory management.
This commit updates the tests to follow the new output for free

procps works well on Linux, on other arches there are some strange
differences due to their emulation of procfs which is not 100%
Disabling checks for non-linux until that can be sorted out.
