Add compat changes for tracing_shell_writable removal.

Commits 7fa51593 and
92fdd895 removed the
tracing_shell_writable and tracing_shell_writable_debug types, and
relabeled the files with debugfs_tracing and debugfs_tracing_debug,
respectively.  Record this in the compatibility file so that vendor
policy using these types will still work.

Bug: 62573845
Test: None. Prebuilt change only.
