[OE-core][PATCH v7 06/12] spdx_common: Check for dependent task in task flags

[Joshua Watt <jpewhacker@gmail.com>]

Checks that the task being used to detect dependencies is present in at
least one dependency task flag of the current task. This helps prevent
errors where the wrong task is specified and never found.
