Alex Richardson ae692c42cb awk: Fix subobject out-of-bounds access
When matching a regex with ^, it would attempt to access
gototab[NSTATES][NCHARS+2], and therefore access the state for the \002
character instead. This change is required to run awk under CHERI (with
sub-object bounds) and when running with UBSan instrumentation.

This was committed upstream as cbf924342b
