deleted /usr/bin/pkexec.security-misc

This was not used anymore for anything. In the past, we used to `config-package-dev` `replace` `/usr/bin/pkexec` with `/usr/bin/pkexec.security-misc` for the purpose of:

* https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=860040
* https://forums.whonix.org/t/cannot-use-pkexec/8129
