fix(tests): set SHELL=sh #24941

Browse Source 
Problem:
Some tests fail with $SHELL=fish #6172
Related: https://github.com/neovim/neovim/pull/6176

Solution:
Replace "echo -n" with "printf", because "echo" in sh may be provided
as a shell builtin, which does not accept an "-n" flag to avoid a
trailing newline (e.g. on macos). "printf" is more portable (defined by
POSIX) and it does not output a trailing newline by itself.
Fixes #6172

TODO:
Other test failures may be related to "session leader" issue: https://github.com/neovim/neovim/issues/2354
Checked by running `:terminal ./build/bin/tty-test` from Nvim with
`shell=/bin/fish` (inherited from `$SHELL`) and it indeed complains
about "process does not own the terminal". With `shell=sh` it doesn't complain. And
unsetting `$SHELL` seems to make `nvim` to fall back to `shell=sh`.
