Allow the PIC's IMR register to be read before ICW initialisation.

As of git submit e179f6914152eca9, the Linux kernel does a simple
probe of the PIC by writing a pattern to the IMR and then reading it
back, prior to the init sequence of ICW words.

The bhyve PIC emulation wasn't allowing the IMR to be read until
the ICW sequence was complete. This limitation isn't required so
relax the test.

With this change, Linux kernels 3.15-rc2 and later won't hang
on boot when calibrating the local APIC.

After r271635 mmap(2) requires either MAP_PRIVATE or MAP_SHARED
for non-anonymous mappings.

This gets 'bhyvectl --get-all' working again.

--version	print the version of mkimg and also whether it's
		64- or 32-bit.
--formats	list the supported output formats separated by space.
