genserv.pl: make external calls safe
By passing command-line as separate arguments instead of using a single
string. This needs skipping the shell, so rework redirections to use
Perl `open3()`.

Also explored to use `-out` to avoid redirections, but it makes the
command-line incompatible with some OpenSSL implementations/versions
(e.g. on default macOS), and would still need a solution for
`2>/dev/null`.

Ref: https://perldoc.perl.org/IPC::Open3

Closes #20971
