qtest: Handle addresses and values for {in, out}[bwl] as unsigned

Handle the addresses and values for {in,out}[bwl] as unsigned (ie
with strtoul), as per the protocol specification comment. This fixes
a test failure in test_i440fx_defaults on 32-bit hosts where the test
tries to write 0x80000000 and qtest was instead writing 0x7fffffff.
