k0kubun 506512c028 spec/ruby: fix RUBY_DESCRIPTION check with JIT enabled
`make test-spec` adds `-r./$(arch)-fake` to pass header options.
But the $(arch)-fake.rb unexpectedly modifies RUBY_DESCRIPTION and it
always drops +JIT from it since the fake.rb is built with BOOTSTRAPRUBY,
which can be miniruby. miniruby can't find MJIT header and thus
mjit_init_p is always FALSE.

So, to pass `make test-spec` with JIT enabled, we can't use
RUBY_DESCRIPTION.
