Revert "Use -fprofile-use= when TEST_SUITE_USE_IR_PGO is enabled"

This reverts commit c1ea19f.

It looks like this is passing the wrong paths to -fprofile-instr-use
now. Previously it passed ${target_path}.profdata.

The new path (${TEST_SUITE_PROFILE_PATH}/${target}.profdat) doesn't
point to the correct location when building via LNT in some
configurations.

Reverting for now to get bots back to green.
