The qemustart script currently picks the ext4 filesystem rather than
squashfs, while the latter is default for nearly all OpenWrt targets.
Change the default behaviour of qemustart to be in line with the rest.

Explicitly set the QEMU cpu type and support the MIPS R2 ISA, for both
64-bit and 32-bit targets. The later previously supported MIPS R2 by
implicit default.
This is needed after commit 93608697f3 ("malta: update MIPS64 ISA to R2"),
otherwise booting malta images with scripts/qemustart will hang.
