Remove libnspr4-dev and nspr-devel
Remove libnspr4-dev and nspr-devel

Since change Ie38deadf190db33863c99d4610157349484ac10f ceilometer does
not use spidermonkey which needed libnspr4-dev (nspr-devel on Red Hat
systems) to be installed. There's
also no other repository using the library.

Thus the requirement can be removed now.
