WebAssembly platforms like wasm32-emscripten and wasm32-wasi don't have a typical user and group database.

WASI platform does not provide necessary API functions at all. Emscripten provides dummy stubs. On Emscripten the pwd module compiles, but is non-functional:

>>> import pwd, os
>>> os.getuid()
>>> pwd.getpwall()
>>> pwd.getpwuid(os.getuid())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'getpwuid(): uid not found: 0'

I propose to make the pwd optional and catch import error in few places where the pwd module is used to look up user home directory.
