[NaCl SDK] nacl_io: Add initial support for getsockopt

Currently there is only support for SO_ERROR which is
used to query the result of non-blocking calls to
connect().  Since out connect() is always blocking
right now this always returns 0.

Also fix a bug in kernel_proxy:socket() where EACCESS
was being returned rather than -1 (with errno set to
EACCESS).

Telemetry: Fix printing of number of failed pages.

Pass 'telemetry_page_measurement_results' as measurement for both metrics.
Distinguish them by passing different values as the trace parameter. This
allows us to show both metrics as separate lines in the same graph.
