Commit 434ce947b09a07dea0733858926a1fa22b761dc7 ("Code formatting + source
cleanup (eclipse)") changed permissions of SCYLLA-VERSION-GEN for no reason.
Fix them up.
This adds version proper version numbering for the scylla-jmx RPM. Please note
that the version number in the server is still hard-coded in the Maven POM
file as "1.0". We need to address that later.
