apps: Fix O_ACCMODE bitmask checks after Linux flag alignment

Browse source 
After aligning NuttX open() flag constants with Linux (O_RDONLY=0,
O_WRONLY=1, O_RDWR=2), code that used '(flags & O_RDONLY)' or
'(flags & O_WRONLY)' as a bitmask check is broken because O_RDONLY
is now 0.  Fix by using '(flags & O_ACCMODE)' comparisons instead.

  - usrsocktest: replace 'flags & O_RDWR' with 'flags & O_ACCMODE'
    in fcntl F_GETFL assertions
  - dd: verify mode used '(oflags & O_RDONLY)' to detect verify;
    replace with '(oflags & O_ACCMODE) == O_RDWR'
  - dpopen: replace '(oflag & O_RDWR) == O_RDWR' with
    '(oflag & O_ACCMODE) == O_RDWR'
  - usbmsc: replace 'flags & O_WRONLY' with
    '(flags & O_ACCMODE) == O_RDONLY'
  - fcntl_test: replace '(flags & O_WRONLY) == 0' with
    '(flags & O_ACCMODE) == O_RDONLY'
