Linux early injection: Handle access to /proc/self/exe by the app

When using early injection, /proc/self/exe is a symlink to libdynamorio.so and not the app's exe.

Using our current early injection approach, I don't know of a way to change this link. We may need to put in a syscall filter that looks for /proc/*/self in calls to readlink() and execve().

This blocks running Chromium tests with -early so I will fix it.
