[PATCH] cangen: allow double value for gap

[Alexander Stein <alexander.stein@systec-electronic.com>]

This way a user can specify a gap below 1ms. This is somehwat similar
to setting the gap to 0, but the ENOBUFS are greatly reduced, so a given
amount of CAN messages by -n is still usefull and useable.
