500_make_backup.sh: fix exit code logic

[casantos]

• Type: Bug Fix

• Impact: Normal

• Reference to related issue (URL): 500_make_backup.sh: filter informational tar messages from output #2466 (comment)

• How was this pull request tested?

Ran a backup ensuring that there is not enough space in the destination to write backup.tar.gz.

• Brief description of the changes in this pull request:

Commit 2674807 removed the BACKUP_PROG_CRYPT_OPTIONS="cat" which breaks
the exit code logic because pipes_rc and backup_prog_shortnames does no
longer match.

Ensure that the number of elements in both variables are alwas the same.

What I like more with your implementation here
compared to my #2472
is that this one here avoids the useless use of cat as dummy.

Now I am wondering if we could also get rid of the useless use of dd
in the other default case when the backup should not be split
with reasonable effort.

On the other hand
#2265
means a complete cleanup of both 500_make_backup.sh
and 400_restore_backup.sh needs to be done at some time anyway.

I wonder if that overall cleanup should be done now or if it is better for now
to not change too much now at once in an hurry and only fix things as they
have been known to work which I tried via #2472

I'm not against a deep overhauling but I'd prefer to do it in baby steps.

Looks good!
