Prefer bash, when running test.sh script

Look for bash, to make it possible to run "make test"
on platforms where it is not the /bin/sh implementation.

It is possible to build ccache without it, when only
running the limited unit tests (with "make quicktest").

 To build ccache from the source repository, you need:
 
 - A C compiler (for instance GCC)
+- GNU Bourne Again SHell (bash) for tests.
 - [AsciiDoc](http://www.methods.co.nz/asciidoc/) to build the documentation.
 - [Autoconf](http://www.gnu.org/software/autoconf/)
