[012568kqv]a: correctly lex full range of integers in the assemblers (thanks Ori_B)

Browse source 
The Plan 9 assemblers use strtoll to parse the integer literals
in their input. It turns out that this is almost correct, but
VLONG_MIN is clamped. This patch changes to use strtoull
in order to allow the full range of integers.
