[PATCH liburing] test: use a map to define test files / devices we need

[Hao Xu <haoxu@linux.alibaba.com>]

Different tests need different files / devices, use a map to indicate
what each test need.

the former implementation use a array for the global list TEST_FILES,
which may causes this:
	TEST_FILES="dev0 dev1"
	dev0 required by test0
	dev1 required by test1
In the <for tst in $TESTS> loop, we run the test for each $dev, which
makes <test0 dev1> and <test1 dev0> run, these are not expected.
Currently I see that statx.c accept argv[1] as a file_name, if someone
writes another test which defines a device(say nvme0n1) in TEST_FILES,
it may cause issues.
