Subject: inherit TAINT_PROPRIETARY_MODULE v2

Hi Jessica,

we've had a bug in our resolution of _GPL modules since day one, that
is a module can claim to be GPL licensed and use _GPL exports, while
it also depends on symbols from non-GPL modules.  This is used as a
circumvention of the _GPL exports by using a small shim module using
the _GPL exports and the other functionality.  A recent example can
be found here:

    https://lore.kernel.org/netdev/6376CA34-BC6F-45DE-9FFD-7E32664C7569@fb.com/T/#md514322fdfa212afe9f1d3eb4e5f7eaefece36eb

Changes since v1:
 - standardize on one spelling of "license"
 - fix a commit message type
