rule-syntax-check: allow commas inside quoted strings

Browse source 
Using a regex to match the groups is smarter than the split(',') that
would break in those cases.

Tested:

  SUBSYSTEM=="usb", ENV{ID_USB_INTERFACES}=="*:060101:*,*:070202:*", TAG+="uaccess"

Rule checker doesn't break there after this commit.
