dirname/basename do not need an external process, shell variable
expansion can be made to do the same a bit faster.

The env-setup script is not intended to be run directly, so it does not
need a shebang line, which might even create the wrong expectations.

'source' is actually a "bashism" and the POSIX-way of sourcing a file
uses the single dot (which is arguably less readable). Both yield the
same result, and since the script may now also be sourced from
within the hacking directory, this commit expands the usage synopsis
accordingly.

Bash needs a special case to determine the dirname of the sourced path
(the hacking dir), but in all other cases, using $0 allows the script to
be sourced also from within the hacking directory, not only from its
parent.
