    Finish move of clock_* functions to libc. [BZ #24959]

    In glibc 2.17, the functions clock_getcpuclockid, clock_getres,
    clock_gettime, clock_nanosleep, and clock_settime were moved from
    librt.so to libc.so, leaving compatibility stubs behind.  Now that the
    dynamic linker no longer insists on finding versioned symbols in the
    same library that originally defined them, we do not need the stubs
    anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases
    for most of the functions anymore either.  (clock_gettime still needs
    one.)  For ports added before 2.17, libc.so needs to provide two
    symbol versions for each, the default at GLIBC_2.17 plus a compat
    version matching what librt had.

    While I'm at it, move the clock_*.c files and their tests from rt/ to
    time/.
