Bump support up to FreeBSD 13 and NetBSD 9.2

These releases are really exciting since they contained the patches we worked to get upstreamed. It means that their /bin/sh interpreters all work fine with Actually Portable Executable now.

+# SYNOPSIS
+#
+#   Actually Portable Python Tutorial
+#
+# DESCRIPTION
+#
+#   This tutorial demonstrates how to compile Python apps as tiny
+#   static multiplatform APE executables as small as 1.9m in size
+#   using Cosmopolitan, which is a BSD-style multitenant codebase
+#
+# GETTING STARTED
+#
+#   # run these commands after cloning the cosmo repo on linux
+#   $ make -j8 o//examples/pylife/pylife.com
+#   $ o//examples/pylife/pylife.com
+#   cosmopolitan is cool!
+#
+# HOW IT WORKS
+#
+#   $ pyobj.com -m -o pylife.o pylife.py
+#   $ ld -static -nostdlib -T o//ape/ape.lds ape.o crt.o \
+#       pylife.o \
+#       cosmopolitan-python-stage2.a \
+#       cosmopolitan-sqlite3.a \
+#       cosmopolitan-linenoise.a \
+#       cosmopolitan-bzip2.a \
+#       cosmopolitan-python-stage1.a \
+#       cosmopolitan.a
+#   $ ./pylife.com
+#   cosmopolitan is cool!
+#
+# NOTES
+#
+#   If you enjoy this tutorial, let us know jtunney@gmail.com. If
+#   you're building something cool, then we can we can add you to
+#   our .gitowners file which grants you commit access so you can
+#   indepnedently maintain your package, as part of the mono-repo

+# We need to define how the repository source code path gets mapped
+# into an APE ZIP file path. By convention, we place Python modules
+# in `.python/` (which is accessible via open() system calls, using
+# the synthetic path `"/zip/.python/"`) which means that if we want
+# to turn `pylife/pylife.py` into `.python/pylife.py` so it's imported
+# using `import pylife` then we can simply append to PYOBJ.COM flags
+# flags above asking it to strip one directory component and prefix
+# Lastly be sure that whenever you use this variable override trick
+# you only do it to .o files, since otherwise it'll ruin everything
+# Passing -m to PYOBJ.COM causes a C main() function to get yoinked
