FIX: with some versions of rsync, option --noatime fails

[atm-florianm]

SellYourSaas seems to be aware of the issue already, but the current detection method (using Ubuntu version) is less reliable than using rsync --help and see if the option is described in the help text.

However, I am not used to executing shell commands from PHP and not comfortable with using the captured stdout. I'm open to better methods (like detecting rsync capabilities only once at install time, in an actual shell script, and storing the detection result in sellyoursaas.conf or any convenient place).

@atm-florianm this is --noatime not --noasync ;-)
