Linux mount/fs (lsblk) facts fixes and tests. (#17036)

Browse Source 
Fixes #10779

Refactor some of the block device, mount point, and
mtab/fstab facts collection for linux for better
performance on systems with lots of block devices.

Instead of invoking 'lsblk' for every entry in mtab,
invoke it once, then map the results to mtab entries.

Change the args used for invoking 'findmnt' since the
previous combination of args conflicts, so this would
always fail on some systems depending on version.

Add test cases for facts Hardware()/Network()/Virtual() classes
__new__ method and verify they create the proper subclass based
on the platform.system() results.

Split out all the 'invoke some command and grab it's output'
bits related to linux mount paths into their own methods so
it is easier to mock them in unit tests.

Fix the DragonFly* classes that did not defined a 'platform'
class attribute. This caused FreeBSD systems to potentially
get the DragonFly* subclasses incorrectly. In practice it
didnt matter much since the DragonFly* subclasses duplicated
the FreeBSD ones. Actual DragonFly systems would end up with
the generic Hardware() etc instead of the DragonFly* classes.

Fix Hardware.__new__() on PY3, passing args to __new__
would cause "object() takes no parameters" errors. So
check for PY3 and just call __new__ without the args

See
https://hg.python.org/cpython/file/44ed0cd3dc6d/Objects/typeobject.c#l2818
for some explaination.
