[pve-devel] [PATCH common] certificate: actually print openssl errors

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

print_errs (which is also called internally by die_now) will only 'warn' the
collected error stack if the log level is set to tracing. otherwise, it will
just return the error message(s) corresponding to the error stack as string.

while they are not always the most user-friendly ones, they do provide
additional context that might help to find out what is actually causing a
particular failure. both helpers here actually provide a meaninful user
friendly context (via $msg) as final line.
