[PATCH RESEND i-g-t v4 18/31] tools/intel_vbt_decode: link with minimal sub-libraries

intel_vbt_decode only needs the chipset tables, half-float conversion
helpers and the lightweight tool stubs used by those helpers.

Switch to linking against lib_igt_chipset, lib_igt_halffloat and
lib_igt_tools_stub instead of the full libigt.so stack.

ldd before: 35  (ldd | wc -l)
ldd after:   4  (ldd | wc -l)
