[ydl-gen] mozilla-xpcom.pc: requires non-existent .pc file

[Joseph E. Sacco, Ph.D.]

/usr/lib/pkgconfig/mozilla-xpcom.pc specifies a non-existent .pc file as
a requirement:

        Requires: mozilla-nspr = 1.7.12

YDL-4.1 does install the nspr-4.6 package, which suggests a fix for
mozilla-xpcom.pc:

        Requires: nspr = 4.6.1
