Properly generate lists of exported symbols for sanitizer runtimes
This change adds a Python script that is invoked for
the just-built sanitizer runtime to generate the list of exported symbols
passed to the linker. By default, it contains interceptors and sanitizer
interface functions, but can be extended with tool-specific lists.
