[Buildroot] [git commit branch/2020.11.x] package/tzdata: drop obosolete, legacy zic option -y

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=de750659bcc9ccf752da3c6aa063bdd3f7bfc639
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.11.x

The following commits:
  - 7868289fd534 package/zic: bump version to 2020f
  - c99374ecbb5e package/tzdata: bump version to 2020f

bumped the tzdata from version 2020a to 2020f. However, in 2020b, the
zic option '-y' was removed, and so was the yearistype.sh script [0].

This now spews annoying warnings:

    warning: -y ignored

Fortunately, it still consumes its argument, so the missing yearistype.sh
is simply ignored.

Drop that option.
