Subject: [PATCH 2/2] lang/ruby27: add DTRACE option

Detecting DTRACE support with hardcoded absolute path is fragile,
add DTRACE option for user to decide. This allows to build ruby27
with non-default toolchain, e.g. devel/llvm12 instead of base one:

compiling dmyenc.c
linking miniruby
ld: error: undefined symbol: __dtraceenabled_ruby___array__create
>>> referenced by array.c
>>>               array.o:(ary_new)
>>> referenced by array.c
>>>               array.o:(rb_ary_new)
>>> referenced by array.c
>>>               array.o:(rb_assoc_new)
>>> referenced 27 more times
