dnsmasq: ensure test and rc order as older than final releases

Opkg treats text after a version number as higher than without:

 ~# opkg compare-versions "2.80rc1" "<<" "2.80"; echo $?
 1
 ~# opkg compare-versions "2.80rc1" ">>" "2.80"; echo $?
 0

This causes opkg not offering final release as upgradable version, and
even refusing to update, since it thinks the installed version is
higher.

This can be mitigated by adding ~ between the version and the text, as ~
will order as less than everything except itself. Since 'r' < 't', to
make sure that test will be treated as lower than rc we add a second ~
before the test tag. That way, the ordering becomes

  2.80~~test < 2.80~rc < 2.80

which then makes opkg properly treat prerelease versions as lower.
