[PATCH nft v2 3/4] tests: shell: README: clarify test file name convention

["Štěpán Němec" <snemec@redhat.com>]

Since commit 4d26b6dd3c4c, test file name suffix no longer reflects
expected exit code in all cases.

Move the sentence "Since they are located with `find', test files can
be put in any subdirectory." to a separate paragraph.

Fixes: 4d26b6dd3c4c ("tests: shell: change all test scripts to return 0")
