[cc/coverage] Pass directory to -fprofile-instr-generate
Bug: http://b/157081822
This will be used if LLVM_PROFILE_FILE is not set at runtime. Some
bionic tests are run without LLVM_PROFILE_FILE set and if they are run
from '/', they fail unable to write to '/default.profraw'. This may
affect other tests as well. Setting this to the value defined by
init.rc.
Test: Enable coverage for bionic, ensure relevant bionic-unit-tests
pass.
