package/apitrace: fix microblaze build failure

Browse Source 
Apitrace is affected by Gcc Bug 68485 that has already been worked
around, but after version bumping, CMakeLists.txt adds -O2 to
CMAKE_C_FLAGS_RELWITHDEBINFO that is in order appended to
CMAKE_C_FLAGS, making -O0 end appending to fail. To prevent this we
need to avoid CMAKE_C_FLAGS_RELWITHDEBINFO to be appended to
CMAKE_C_FLAGS, so let's do the same as flare-engine package that set
CMAKE_BUILD_TYPE to a fake build type called "buildroot", this way -O2
won't be appended after -O0 and work around restart to work as
expected.
