ports/89052: [patch] www/mozilla: Fix ld-run-path issue in libraries

[Mikhail Teterin]

A minor nit -- the encoded rpath (in the new CONFIGURE_ENV) should begin with 
${PREFIX}, rather than ${X11BASE}...

Also, rather than patching stuff under mozilla's own nsprpub/, mozilla should 
be using devel/nspr (and security/nss) and avoid even extracting the 
redundant subtrees.

Firefox is already doing that...
