[ Upstream commit 3d07b691ee ]

With the inclusion of commit c259acab83 ("ptp/ioctl: support
MONOTONIC{,_RAW} timestamps for PTP_SYS_OFFSET_EXTENDED") clock_gettime()
now allows retrieval of pre/post timestamps for CLOCK_MONOTONIC and
CLOCK_MONOTONIC_RAW timebases along with the previously supported
CLOCK_REALTIME.

This patch adds a command line option 'y' to the testptp program to
choose one of the allowed timebases [realtime aka system, monotonic,
and monotonic-raw).
