[Buildroot] [git commit branch/2022.02.x] packages/sudo: explicitly set with-tzdir

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=2a6da8d48660027c48a007394b10369e277b3741
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.02.x

sudo's configure script looks up on the host to determine the path to
the timezone data location. That fails in cross-compilation.

This is used to sanitise the TZ envirnment variable at runtime, and is
not used at buildtime (except to be stored as a string in the program).

We can tell sudo where the tz data will be, which we do when the tzdata
package is enabled, and we can tell it not to use it at all (to not pass
TZ down to sudo-ed executions) othwerwise.
