package/ncdu: bump to version 1.21

For change log since 1.20, see:
https://dev.yorhel.nl/ncdu/changes

This commit also update the _SITE URL to use https.

The autoconf configure script of this new version (generated with
autoconf 2.72) now requires pkg-config. Therefore, this commit also
adds host-pkgconf in _DEPENDENCIES.
