remove obsolete patch

The patch was necessary for earlier versions. When the culprit in lcms
was partially reverted this triggered me rewriting the patch instead of
dropping it: the amended parameters in that call-chain were not needed
any more since commit c9f2256 in lcms2mt. So drop the patch.

-Subject: [PATCH] fix build on big endian
-
-0dc1153 ("Spread of context into all procedures and removal from
-structures", 2017-04-26) missed a few spots that are relevant on big
-endian only.
-
-Add the missing ContextIDs in the call chain so that the build succeeds
-again.
