coredump: Fix missing loglevel to logmask conversion.

The current setlogmask call used in coredump_dump_syslog specifies a raw log level
instead of a bitmask, and this causes wrong evaluations later on when that value
is checked against a mask. Therefore the LOG_UPTO macro is added for conversion.
