mmc-utils: update to upstream's 8f41ccbb40b8 commit

Summary of upstream's highlight changes:
- recognize ext_csd_rev 9
- fix CID manufacturing date decoding
- add ability to flush optional eMMC cache
- upcoming versioning
- RPMB handling refactoring
- improved FFU support
- doc/help refactoring/cleanups

This also requires updating our patch for fortify-ing and
we need to add a flag to disable a call to 'sparse' tool.

+Subject: [PATCH] Drop _FORTIFY_SOURCE and prevent calls to git
+
+The fortify level is set globally in OpenWrt so it would
+be redefined when passed via CFLAGS and it would trigger
+a build error. To prevent this, dont set it here. Later,
+the previously/globally defined one (the OpenWrt one) is
+passed, but then unset and re-set again via Makefile to
+the originally desired one.
+
+Comment also out calls to git for version detection.
+We pass the version from the package definition to Makefile
+and operate not on a git checkout thus the calls would fail.
