Alexander Reelsen 7b64a5c2c8 Packaging: Check if proc file exists before calling sysctl
The packaged init scripts could return an error, if the file
/proc/sys/vm/max_map_count was not existing and we still called
sysctl.

This is primarly to prevent confusing error messages when elasticsearch
is started under virtualized environments without a proc file system.
