app-crypt/rhash: Install libs, respect flags, nls, openssl, tests

* Install the shared and (optionally) static libraries.
* Multilib support for the libraries.
* Respect CC, CFLAGS, LDFLAGS.
* gettext support via nls flag.
* Additional hash support via openssl.
* Passing test suite.
* Disable debug by default.

These changes were made with sbraz's blessing. Thanks to Raimonds
Cicans for the initial work behind this.
