linux: print a better message for "out of memory" errors for kernel filters.

If attempting to set a kernel filter gets ENOMEM, print a message
suggesting that they increase the value of the net.core.optmem_max
sysctl.

See GitHub issue #1089 for an example of a complicated but not too
complicated filter that exceeds the default "other/option memory per
socket" maximum.
