[RFC PATCH v2 1/4] btrfs-progs: Add package command for packaging tests

[Gu Jinxiang <gujx@cn.fujitsu.com>]

Export the testsuite files to a separate tar.
Since fsck tests depend on btrfs-corrupt-block, and misc
tests depends on both btrfs-corrupt-block and fssum,
so set it as prerequisites for package commad.

Because,
althougth fssum can be generated by source that are all in
tests directory, and has no rely on the btrfs's structure.
But btrfs-corrupt-block deeply relys on btrfs's structure.
For consistency, at the present stage, generete the two
when create test tar.
