[PATCH] test: test-lib.sh: use $BASH instead of ${SHELL-sh} to relaunch

[Tomi Ollila]

In case of the test script is to be relaunced under valgrind, or --tee
is requested, use the $BASH shell variable to locate the command
interpreter.
The $SHELL environment variable is not set by bash if it already
had non-empty value (e.g. "/bin/zsh").
After this change requesting script relaunch from users' "incompatible"
(i.e. not bash 4.x) cli SHELLs will work.
