hyperscan: remove package

Remove hyperscan since Intel announced a proprietary/closed source
license beginning with hyperscan 5.5[1,2] and a general lock of support
for the 5.4.x branch which has not seen a commit since 19-Apr-2023[3].

-Subject: [PATCH] CMakeLists.txt: hack for our build system
-
-If building with the project external toolchain, the gcc check
-fails to set the correct value for TUNE_FLAG to allow the min
-supported SSSE3 compiler support test to pass.  This patch hacks
-the file to set to the correct value.
