popt: remove libintl static linking handling

We no longer support building the full-blown libintl in static linking
scenarios, as it causes too many problems. Therefore, remove the patch
that was handling this.

-Subject: [PATCH] popt.pc: add the libintl library to the Libs.private field
-
-If static linking and libintl is used, the program that uses the popt
-library needs to link to the libintl library too so add the libintl
-library to the libs.private field because is useful for programs that call
-  pkg-config --static --libs popt
-they get the libintl library too:
-  -L<...> -lpopt -lintl
-
-This patch was already sent upstream:
-http://rpm5.org/community/popt-devel/0294.html
