[Buildroot] [PATCH v2 2/5] support/testing: add new test for python-pymupdf

[Raphaël Mélotte]

To give us a chance to catch runtime issues (such as missing
dependencies) more easily, add a test that writes a sample PDF file,
read it back and verify the text that was read.

Like similar packages that lead to a big
rootfs (e.g. python-botocore), this test requires a separate ext2
rootfs to avoid filling the default amount of RAM available
entirely (which would cause missing files from the root filesystem and
in turn, test failures).
