4b0f010b88 MDEV-18544 "missing required privilege PROCESS on *.*" using mariabackup for SST
If required privilege is missing, dump the output from "SHOW GRANTS"
into mariabackup log.

This will help troubleshooting, and make the bug reproducible.

5716c71c54 MDEV-14975 mariabackup starts with unprivileged user.
ported privilege checking from xtrabackup.
Now, mariabackup would terminate early if either RELOAD or PROCESS privilege
is not held, not at the very end of backup

The behavior can be disabled with nre setting --check-privileges=0.
Also , --no-lock does not need all of these privileges, since it skips
FTWRL and SHOW ENGINE STATUS INNODB.
