package/x11r7/xlib_libXfont2: fix libbsd detection
Previous patch defined HAVE_LIBBSD even if strlcat function was present
in libc leading to build errors due to inclusion of bsd/string.h:
https://gitlab.freedesktop.org/xorg/lib/libxfont/blob/master/src/util/replace.h#L50
AC_SEARCH_LIBS is defined as
"Search for a library defining function if it's not already available."
