Summary: On macOS, we can't do the DYLD_INSERT_LIBRARIES trick with a shim python binary as the ASan interceptors get loaded too late. Find the "real" python binary, copy it, and invoke it. Hopefully this makes the GreenDragon and swift-ci sanitizer bots happy... I tested this out by running `../llvm-macosx-x86_64/bin/llvm-lit test --filter TestNSDictionarySynthetic.py` in an ASanified swift-lldb build directory and it worked (i.e. no more "interceptors loaded too late" messages).

# On macOS, system python binaries like /usr/bin/python and $(xcrun -f python3)

|
# are shims. They do some light validation work and then spawn the "real" python
|
|
# binary. Find the "real" python by asking dyld -- sys.executable reports the
|
|
# wrong thing more often than not. This is also useful when we're running under
|
|
# a Homebrew python3 binary, which also appears to be some kind of shim.
