Loosen up modem regexp in cromo init
Loosen up modem regexp in cromo init

We are seeing device names of 1-6.3 instead of 1-6 when we look at the
udev device for our driver.  Make the regexp for validating pathnames
more liberal to accept this.  We still don't accept /, so this should
be security-neutral

BUG=15487
TEST=network_3GRecoverFromGobiDesync + manually add a bogus device to /var/run/cromo/usb-devices and check for debug output
