rGf239db4800ee: ktrace: Remove CAPFAIL from default trace points

Summary

The CAPFAIL tracepoint was recently modified to report capability
violations for processes that do not enter capability mode. This
allows developers that are interested in Capsicumizing their programs
to determine where violations are being raised.

Having this tracepoint enabled by default may lead to confusion for
users that are not familiar with the feature. Remove KTRFAC_CAPFAIL from
ktrace's default points to avoid this.

I would point out in the commit message that, before your commits, CAPFAIL was basically never used, so users are very unlikely to notice the change in defaults.
