[libvirt PATCH] virsh: guest-agent-timeout: set default value for optional argument

[Tomáš Golembiovský <tgolembi@xxxxxxxxxx>]

The timeout argument for guest-agent-timeout is optional but it did not
have proper default value specified. Also update the virsh man page
accordingly.

-* -1 - reset timeout to the default value,
+* -2 - block forever waiting for a result (used when --timeout is omitted),
