travis: Move fastest test configuration first

I use Travis CI to check each patch before sending my patchsets.  Most
failures are simple and make all test configurations fail.  However, since
Travis CI runs test configurations in order and given that the first three
configurations are the slowest ones, it takes about twenty minutes to see
the failure.  Moving the fastest test configuration first would allow to
fail earlier.  It would become about 3x faster to fail in case of simple
mistakes.

* .travis.yml (CC=gcc, STACKTRACE=no): Move to first position.

(SO_SNDTIMEO): Rename to SO_SNDTIMEO_OLD.

Rename SO_TIMESTAMP* to SO_TIMESTAMP*_OLD

Follow the Linux kernel commit v5.1-rc1~178^2~363^2~8 and rename
these constants everywhere.

* xlat/scmvals.in (SO_TIMESTAMP): Rename to SO_TIMESTAMP_OLD.

Replace SCM_TIMESTAMP* constants with SO_TIMESTAMP*

Besides the fact that SO_TIMESTAMP* constants appear to be more
standardized than SCM_TIMESTAMP*, new SO_TIMESTAMP*_OLD and
SO_TIMESTAMP*_NEW constants introduced in Linux 5.1 have no
SCM_TIMESTAMP*_OLD and SCM_TIMESTAMP*_NEW analogues.

* xlat/scmvals.in: Replace SCM_WIFI_STATUS, SCM_TXTIME, SCM_TIMESTAMP,
SCM_TIMESTAMPNS, and SCM_TIMESTAMPING with SO_WIFI_STATUS, SO_TXTIME,
SO_TIMESTAMP, SO_TIMESTAMPNS, and SO_TIMESTAMPING, respectively.

SCM_TIMESTAMPNS with SO_TIMESTAMP and SO_TIMESTAMPNS, respectively.

tests: add another test of SO_TIMESTAMP and SO_TIMESTAMPNS decoding

Unlike msg_control test, this new test makes the kernel generate
SO_TIMESTAMP and SO_TIMESTAMPNS messages.

* tests/sockopt-timestamp.c: New file.
* tests/gen_tests.in (sockopt-timestamp): New entry.
