gpsd: Update to 3.20, add/refresh patches

New patches (both for SConstruct):

* Do not import from distutils. Since Python support/modules are not
  built, there is no need to import from distutils. (Importing from
  distutils may prevent the package from being built on systems without
  a full distutils module, e.g. Debian with python3-minimal.)

  I have added back the import in places where it may be helpful to
  have, if scons is run manually.

  Fixes #10993.

* Do not check the size of time_t. The way this is done is to compile
  and run a test program; this fails when cross-compiling[1].

  This doesn't appear to affect any functionality (other than missing a
  compile-time warning that things will fail in 2038 if time_t is too
  small).
