Fix cap drop issues with lxc

This uses "," instead of spaces so that the flags are parsed correctly
and also does not do a strings.Split on an empty string because
strings.Split will return a slice with one element, and empty string
causing parsing to fail when it validates that the cap exists.

pkg/units: Standardized supported sizes

May make sense that both `FromHumanSize()` and `RAMInBytes()` support
the same units. Added 'PB' to the RAMInBytes regex.

Also updated tests.

Note: int64 is overflowed on quantities >= EB

pkg/units: Refactored common code to single func

Both functions perform the same logic and they just vary on the base
multiplication units. We can refactor the common code into a single
place.
