rtklib: add test.sh and test-version.sh for CI

The RTKLIB command-line tools (convbin, pos2kml, rnx2rtkp, rtkrcv,
str2str) don't accept a --version flag; passing any unrecognized option
triggers printhelp()/printusage() which only emits a synopsis block. The
generic CI version probe therefore can't find PKG_VERSION and marks the
package as missing a version match.

Add a test-version.sh that exit-0's for all five subpackages to skip the
generic version check, and a test.sh that exercises each binary's
synopsis output as a basic functional smoke test.
