package/libmcrypt: drop package

Drop libmcrypt which is a cryptographic package that is not maintained
anymore. Here is an extract of https://en.wikipedia.org/wiki/Mcrypt:
"The last update to libmcrypt was in 2007, despite years of unmerged
patches. These facts have led security experts to declare mcrypt
abandonware and discourage its use in new development.".
