[PATCH for-9.0 v2 4/7] qtest/virtio-9p-test.c: consolidate create file tests

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

Similar to what was done with fs_create_dir() in the previous patch, and
for the same reasons, let's consolidate fs_create_file() and
fs_unlinkat_file() in a single test that has the same coverage:

- fs_create_file() is removed;

- rename fs_unlinkat_file() to fs_create_unlinkat_file();

- change fs_create_unlinkat_file() to also remove the created dir.

The remaining tests got their dir changed to reflect that we're now with
one less test.
