FreeBSD/ports e587481 (r437019)graphics/libkexiv2-kde4 Makefile pkg-plist

Stop installing the .pc file with a different name.

Use the default one: graphics/libkexiv2 has not existed in the tree since 2013,
and the x11/kdelibs4 update from r436971 removed a patch to FindKexiv2.cmake we
used to look for libkexiv2-kde4.pc. In practice, this commit unbreaks ports
that depended on graphics/libkexiv2-kde4 after the kdelibs4 update I mentioned.
