x86/tools: objdump_reformat.awk: Allow for spaces
GNU objdump and LLVM objdump have differing output formats.
Specifically, GNU objump will format its output as: address:<tab>hex,
whereas LLVM objdump displays its output as address:<space>hex.
objdump_reformat.awk incorrectly handles this discrepancy due to
the unexpected space and as a result insn_decoder_test fails, as
its input is garbled.
The instruction line being tokenized now handles a space and colon,
or tab delimiter.
