timezone: add a configure flag to disable program install
Some distros build+install the timezone tools (zic/zdump/tzselect) outside of glibc and use the upstream package directly. Add a configure flag to glibc so they can disable install of those tools. This allows tests to run & pass regardless of the configure flag. Only the install of them is impacted.

+ By default, timezone related utilities ('zic', 'zdump', and
