gettext_0.16.1: remove obsolete uclibc specific patch

gettext-error_print_progname.patch was originally created for gettext
v0.14.6 and does not apply cleanly to gettext v0.16.1.

Since the original issue addressed by the patch isn't documented and
because gettext v0.16.1 seems to be build OK for uclibc without the
patch, assume the patch is obsolete and no longer required.
