io: Fix F_GETLK, F_SETLK, and F_SETLKW for powerpc64
Different than other 64 bit architectures, powerpc64 defines the LFS POSIX lock constants with values similar to 32 ABI, which are meant to be used with fcntl64 syscall. Since powerpc64 kABI does not have fcntl, the constants are adjusted with the FCNTL_ADJUST_CMD macro. The 4d0fe291aed3a476a changed the logic of generic constants LFS value are equal to the default values; which is now wrong for powerpc64. Fix the value by explicit define the previous glibc constants (powerpc64 does not need to use the 32 kABI value, but it simplifies the FCNTL_ADJUST_CMD which should be kept as compatibility). Checked on powerpc64-linux-gnu and powerpc-linux-gnu. (cherry picked from commit 5f828ff824e3b7cd133ef905b8ae25ab8a8f3d66)
