Fix build against binutils >= 2.44.

Two independent breakages, both from libopcodes/libbfd churn:

1. honggfuzz decides which disassembler() prototype to use by probing
   for FOR_EACH_DISASSEMBLER_OPTION, a macro added to dis-asm.h in
   binutils 2.29. That macro is gone from current dis-asm.h, which
   superseded it with the disasm_options_t machinery, so the probe now
   silently selects the pre-2.29 branch and calls disassembler() with
   one argument where the header declares four.

   The probe is dead weight regardless: the ebuild already floors
   RDEPEND at >=sys-libs/binutils-libs-2.29, so the legacy branch is
   unreachable. Drop the probe and keep only the modern call.

2. bfd.h no longer defines TRUE/FALSE; current binutils uses the C99
   bool, which honggfuzz already has in scope via honggfuzz.h -> 
   <stdbool.h>. Three uses remain in linux/bfd.c: two
   bfd_find_nearest_line() comparisons and the `bool big` argument of
   disassembler().

Symptom note: because TRUE/FALSE are undeclared, GCC also reports
"too few arguments to function 'disassembler'" on the same line. That
is error recovery noise, not a third defect.

Not submitted upstream: the last tagged release is 2.6 and the only
activity since is the rolling "oss-fuzz" tag from 2024-07.
