COMP: Fix OpenSSL install rules

Commit r22724 updated the External_* project files to support
Slicer_USE_SYSTEM_* variables. For sake of consistency, it also
changed variable "EP_OpenSSL_LIBRARIES" into "OPENSSL_LIBRARIES".
Since not all variables have been updated, this commit updates
the remaining variables to fix the OpenSSL install rules.
