x86/tools: Drop duplicate unlikely() definition in insn_decoder_test.c

After commit c104c16073b7 ("Kunit to check the longest symbol length"),
there is a warning when building with clang because there is now a
definition of unlikely from compiler.h in tools/include/linux, which
conflicts with the one in the instruction decoder selftest:

  arch/x86/tools/insn_decoder_test.c:15:9: warning: 'unlikely' macro redefined [-Wmacro-redefined]

Remove the second unlikely() definition, as it is no longer necessary,
clearing up the warning.

Fixes: c104c16073b7 ("Kunit to check the longest symbol length")
