[PATCH 07/12] test/9pfs: change export tag name to qtest-synth

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

All existing 9pfs test cases are using the 'synth' fs driver so far, which
means they are not accessing real files, but a purely simulated (in RAM
only) file system.

Let's start to make this clear with this and the following patch to pave
the way for upcoming new tests going to use the 9pfs 'local' driver
instead.

This patch starts by changing the 9p tag name (which identifies one
particular 9p exported file tree) from 'qtest' to 'qtest-synth' and also
change the preprocessor macro used for this from TAG_NAME to TAG_NAME_SYNTH.
