cmake: Fix ext/hal/ti/simplelink/CMakeLists.txt

After the cmake conversion, the SimpleLink WiFi host
driver would not build, and compiler flags like -Wno-strict-aliasing
were not being applied as they got spliced in before
-Wall rather than after.

This fixes those issues, using the set_source_files_properties()
method as suggeted in the CMakeLists.txt TODO comment.
