serve: accept multiple values for --daemon-postexec

The next patch will add another postexec command: chdir, which can be used
together with unlink. This patch changes the option type of --daemon-postexec
from string to list to accept multiple commands. The error message of invalid
--daemon-postexec value is also changed to include the actual invalid value.
