coredumpctl: rework presence reporting
The column for "present" was easy to miss, especially if somebody had no coredumps present at all, in which case the column of spaces of width one wasn't visually distinguished from the neighbouring columns. Replace this with an explicit text, one of: "missing", "journal", "present", "error". $ coredumpctl TIME PID UID GID SIG COREFILE EXE Mon 2016-09-26 22:46:31 CEST 8623 0 0 11 missing /usr/bin/bash Mon 2016-09-26 22:46:35 CEST 8639 1001 1001 11 missing /usr/bin/bash Tue 2016-09-27 01:10:46 CEST 16110 1001 1001 11 journal /usr/bin/bash Tue 2016-09-27 01:13:20 CEST 16290 1001 1001 11 journal /usr/bin/bash Tue 2016-09-27 01:33:48 CEST 17867 1001 1001 11 present /usr/bin/bash Tue 2016-09-27 01:37:55 CEST 18549 0 0 11 error /usr/bin/bash Also, use access(…, R_OK), so that we can report a present but inaccessible file different than a missing one.
