[PATCH v2 1/1] bitbake.conf: fix vardepsexclude for ZSTD_DEFAULTS

["'Benedikt Niedermayr' via isar-users" <isar-users@googlegroups.com>]

This fixes a rebuild in case ZSTD_LEVEL changes. This is valid since
a different compression level leads to different outputs.

This patch copies the current implementation from OE and thereby
fixing this issue in order to be more aligned with the OE
naming convention.
