ruby.c: remove a magic number

Browse source 
* ruby.c (load_file_internal): remove a magic number, which means
  the length of ruby_engine but the value is unknown in this file
  since the variable is in a different file now.  instead, strstr
  should deal with it well, as far as ruby_engine does not contain
  a space and a hyphen.
