utils: aa-genprof fails on lxd with OSError: Read-only file system

Browse source 
On certain lxc containers, when aa-genprof tries to set
printk_ratelimit, it fails with the OSError exception, with the
message "OSError: [Errno 30] Read-only file system" instead of
PermissionError.

Since PermissionError is a subclass of OSError, replace it by broader
OSError exception to include both cases in which running aa-genprof
fails.
