[asan] Support running without /proc
Summary:
This patch lets ASan run when /proc is not accessible (ex. not mounted
yet). It includes a special test-only flag that emulates this condition
in an unpriviledged process.
This only matters on Linux, where /proc is necessary to enumerate
virtual memory mappings.
