Leave Jenkinsfile alone

[wyuenho]

The regex currently will match any file that contains the substring Jenkinsfile, which means when I visit jenkinsfile-mode.el, the major mode will switch to groovy-mode even when I'm looking at an elisp file.

There's a much better mode for Jenkins out there already, leave syntax highlighting to that mode.

Thanks for the report! Users are free to load other packages and choose what to prioritise in auto-mode-alist, but I agree we shouldn't match other files.

@Wilfred you just broke Jenkinsfile matching :) This regex matches full path, so instead ^ there should be /.
