Add gmp as a dependency of Ruby to accelerate Bignum (closes #506).

* Ruby has supported optionally using the GMP library to accelerate the
  `Bignum` class since version 2.1.0.
  https://bugs.ruby-lang.org/issues/8796
* Installing the GMP library by default should improve the performance of
  `Bignum`.
