[coverage] Wrap calls to open
Bug: http://b/173448692
The coverage runtime creates files with uga+rw permissions but an
earlier umask call can restrict these and cause problems with profile
merging ('%Nm' in LLVM_PROFILE_FILE). This change passes `--wrap,open`
to coverage builds. The other change in this topic adds the wrapper
function to set the permissions again using `fchmod` (only for files
opened under /data/misc/trace).
Test: Manually validate permissions of files under /data/misc/trace.
Test: libprofile-clang-extras-test
