Upgrade setuptools from 49.1.0 to 49.2.0

[asherf]

v49.2.0

• Fixup GoFetch to handle relative imports. #2230: Now warn the user when setuptools is imported after distutils modules have been loaded (exempting PyPy for 3.6), directing the users of packages to import setuptools first.

v49.1.3

• Transition IvyImports to 'compile_classpath'. #2212: (Distutils) Allow spawn to accept environment. Avoid monkey-patching global state.
• Add support for resources to GoWorkspaceTask #2249: Fix extension loading technique in stubs.

v49.1.2

• Only cache classes inside the context jar, and then extract it after a hit. #2232: In preparation for re-enabling a local copy of distutils, Setuptools now honors an environment variable, SETUPTOOLS_USE_DISTUTILS. If set to 'stdlib' (current default), distutils will be used from the standard library. If set to 'local' (default in a imminent backward-incompatible release), the local copy of distutils will be used.

v49.1.1

• Pl.jvm missing dep compile classpath #2094: Removed pkg_resources.py2_warn module, which is no longer reachable.

v49.0.1

• [Trigger CI] Include resolved jar versions in compile fingerprints; ensure coordin… #2228: Applied fix for command.build_ext raises FileNotFoundError pypa/distutils#3, restoring expectation that spawn will raise a DistutilsExecError when attempting to execute a missing file.
