perf build: Move libopcode disasm tests to BUILD_NONDISTRO

The disasm feature tests feature-disassembler-four-args and
feature-disassembler-init-styled link against libopcodes part of
binutils which is license incompatible (GPLv3) with perf. Moving these
tests out of the common config will help improve build time.
