Log Message:
Fix target location of copied config files for chat/gale.

Use ${PKG_SYSCONFDIR}, not ${PKG_SYSCONFDIR}/gale, to refer to the
config directory -- since PKG_SYSCONFSUBDIR is set to "gale",
${PKG_SYSCONFDIR} already includes that subdirectory.

Remove ${PKG_SYSCONFSUBDIR} from OWN_DIRS, since the config
directory is already automatically created by the package install
scripts if PKG_SYSCONFSUBDIR is set.

Bump the PKGREVISION due to the changes in the package install
scripts.
