autotools: copy also remove-potcdate.sin from ${STAGING_DATADIR_NATIVE}/gettext/po
* some packages (e.g. uptime, cpu, forecasts, news from meta-efl)
don't have remove-potcdate.sin in po subdirectory, but Makefile.in.in
supplied by autotools.bbclass depends on it and fails without like this:
| make[3]: Entering directory `/OE/shr-core/tmp-eglibc/work/x86_64-oe-linux/uptime/0.0.2+svnr80477-r0.0/E-MODULES-EXTRA/uptime/po'
| make[3]: *** No rule to make target `remove-potcdate.sin', needed by `remove-potcdate.sed'. Stop.
| make[3]: Leaving directory `/OE/shr-core/tmp-eglibc/work/x86_64-oe-linux/uptime/0.0.2+svnr80477-r0.0/E-MODULES-EXTRA/uptime/po'
| make[2]: *** [uptime.pot] Error 2
