Update shell files to use /bin/bash and POSIX .

bash's earlier problems with subshells running scripts starting #!/bin/bash
seem to be solved, so explicitly mark all scripts as requiring bash.
Furthermore, change all source built-ins to prefix the path with "./" as
required by POSIX. Together these changes should stop further problems
with changes of source built-in semantics in future.
