Disable file watching when running tests headlessly

[jennifer-shehane]

I'm getting an ENOSPC error when running my tests headlessly using cypress ci. This is generally due to the system reaching it's limit on how many files can be watched.

Cypress should not be watching any files while running headlessly.

Fyi, this is currently blocking us because the workaround[1] for increasing the watch limit isn't allowed inside docker (Read only file system for sysctl). docker build simply doesn't allow this and with docker run, requires --privileged option which is undesirable.
