misc/build_helpers/test-osx-pkg.py: script to test the OS X pkg.

After extracting the contents of the package, this script looks at the
output of 'tahoe --version-and-path' to see if the modules are installed
and invoked from the right path.

+# This script treats the OS X pkg as an xar archive and uncompresses it to
+# the filesystem. The xar file contains a file called Payload, which is a
+# gziped cpio archive of the filesystem. It then cd's into the file system
+# and executes '$appname --version-and-path' and checks whether the output
+# of that command is right.
+
+# If all of the paths listed therein are loaded from within the current PWD
+# then it exits with code 0.
+
+# If anything goes wrong then it exits with non-zero (failure).  This is to
+# check that the Mac OS '.pkg' package that gets built is correctly loading
+# all of its packages from inside the image.
