Added gitignore for bats repository

invoke make update-gems before make install with ruby-trunk

- Only call `openssl version` once;

- Make the check work with future version of LibreSSL after 2.2.7. This
  assumes that Apple might keep updating LibreSSL shipping with macOS,
  but that they will never provide header files.

To use standard_build and standard_install_with_bundled_gems for ruby versions that has bundled gems

  * standard_build invoke configure and make. It not invoke `make install`.
  * standard_install invoke only `make install`.
  * Added backword compatibility function for above separation.
  * Added new function for bundled_gems support named standard_install_with_bundled_gems.
