CVE-2021-23215/openexr: clarify patches some more
(Following prompt by carnil)

de27156 is a pre-requisite for the 2.x branches (especially our 2.2.x versions).
Without it (especially chunk #4 whose code range is untouched by the other patch) the test suite fails.

$ ./IlmImfTest testCompression
tempDir = /var/tmp/IlmImfTest_ODOFNYZG
