Header-only devel package PROVIDES field fixes (ROCm#170)

* Fix provides field

Previously the code for provides field was not evaluating the CPACK_DEBIAN_PACKAGE_PROVIDES variable, causing CPACK_DEBIAN_PACKAGE_PROVIDES to be included as a literal string provided by the devel package.

* Correct debian/rpm

* Fix misplaced comma

* Remove version from RPM provides field
