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.
