[tz] [PROPOSED] Restore SUPPRESS_TZDIR support if OPENAT_TZDIR

[Paul Eggert via tz]

The 09-28 changes inadvertently removed some support for the
rarely-used SUPPRESS_TZDIR option.
* localtime.c (tzloadbody) [OPENAT_TZDIR && SUPPRESS_TZDIR]:
Do not open TZDIR, as when SUPPRESS_TZDIR we want relative
pathnames to be relative to the working directory, not to TZDIR.
