  Log Message:
  -----------
  Fix detection of clock_gettime() and clock_nanosleep()

glibc above 2.17 has these functions builtin, so no need to link against librt.

When the macro succeeds, it needs to set the define to 1, not 0.

Also clarify the text message if librt is linked in.

    M drivers/dummy/dummy_driver.h

  Log Message:
  -----------
  Use #if for HAVE_CLOCK_GETTIME in dummy driver

ifdef is useless, since the value is always defined (either to 1 or 0) in config.h.

  Changed paths:
    M jackd/engine.c
    M libjack/time.c

  Log Message:
  -----------
  Use #if for HAVE_CLOCK_GETTIME everywhere

ifdef is useless, since the value is always defined (either to 1 or 0) in config.h.

Fix inspired by

  https://svnweb.freebsd.org/ports/head/audio/jack/files/patch-drivers_dummy_dummy__driver.c?view=markup

Also simplified #if condition in libjack/time.c - it's easier to read a positive than a negated
condition.
