readhead: temporarily lower the kernel's read_ahead_kb setting while collecting
While collecting readahead data we want to know exactly what userspace
accesses unblurred by the kernel's read_ahead_kb. Hence lower this
during collection, and raise it afterwards.
This is mostly based on ideas and code by Auke Kok.
