     xfstests: use native definition of O_DIRECT flag

     The definition of O_DIRECT in src/trunc.c causes xfstest 125 to fail
     when run on a Pandaboard.  On ARM, the value used (0x040000) is
     O_DIRECTORY rather than O_DIRECT as it is on x86.  Prefer the 
platform's
     native definition of O_DIRECT supplied by fcntl.h if available.  Also,
     fix a couple of error messages to properly reflect their context.
