Fixes #3628 Remove memory check

Removes the memory check, as this is incorrect for a 8GB macbook that
is capable of running MicroShift. Lowering the check makes this less
relevant/meaningless; it says nothing about the ability in that case
to run any of the supported presets. Any check needs to happen from the
preset specific default values on startup, not installation.
