[PATCH v2 3/3] t1301: do not change $CWD in "shared=all" test case

[Jiang Xin <worldhello.net@gmail.com>]

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

In test case "shared=all", the working directory is permanently changed
to the "sub" directory. This leads to a strange behavior that the
temporary repositories created by subsequent test cases are all in this
"sub" directory, such as "sub/new", "sub/child.git". If we bypass this
test case, all subsequent test cases will have different working
directory.

Besides, all subsequent test cases assuming they are in the "sub"
directory do not run any destructive operations in their parent
directory (".."), and will not make damage out side of $TRASH_DIRECTORY.

So it is a safe change for us to run the test case "shared=all" in
current repository instead of creating and changing to "sub".

For the next test case, we no longer run it in the "sub" repository
which is initialized from an empty template, we should not assume the
path ".git/info" is missing. So add option "-p" to mkdir.
