Dan McGee ef4757afa5 Store a package info level flag if we fail to load data
If we are missing a local database file, we get repeated messages over
and over telling us the same thing, rather than being sane and erroring
only once. This package adds an INFRQ_ERROR level that is added to the
mask if we encounter any errors on a local_db_read() operation, and
short circuits future calls if found in the value. This fixes FS#25313.

Note that this does not make any behavior changes other than suppressing
error messages and repeated code calls to failure cases; we still have
more to do in the "local database is hosed" department.

Also make a small update to the wrong but unused flags set in
be_package; using INFRQ_ALL there was not totally correct.
