Handle optional ipconfig timeout

Specify timeout for ipconfig so that we can still boot while network is done.
Otherwise ipconfig remains stuck (until IP can be configured). If not given
we default to 10s.

Minor code refactoring.

Moved configuration file from /etc/dropbear/initrd.env to /etc/initcpio/sshcs_env since
it now contains options for ipconfig and not only dropbear. Package installation script
move legacy file to new path if present.
