[Libguestfs] [PATCH] test-charset-fidelity: allow to skip testing specific FSes

[Pino Toscano]

Allow to skip testing the filesystem "foo" if the environment variable
SKIP_TEST_CHARSET_FIDELITY_foo=1 is set. This way it possible to not
test one or more filesystems without disabling the test altogether.
