Log Message:
Put the charset.alias file into place using REQD_FILES instead of
CONF_FILES since we need it to always be present for libiconv to
function properly.  It's now no longer removed automatically at
deinstallation if it differs from the stock charset.alias file, meaning
it's now preserved in case the user made modifications to the file;
however a warning will be output that the file can be safely removed
if you don't need it anymore.  Bump the PKGREVISION to 1.
