autoconf: Add fix for sh verses bash issues

Libtool scripts were finding bash was /bin/sh and then using bashisms which
then got into sstate and used on machines where /bin/sh might be dash.

This changes things to search for bash first since its preferred. We then hardcode
bash into the scripts which is more correct.

This does mean we have a dependency on bash but many of our scripts have
that anyway.

+This value is used to determine CONFIG_SHELL and SHELL which may get exported into
+scripts shared via sstate onto other systems.
+
+Some systems have /bin/sh -> dash and others /bin/sh -> bash. Bash is preferred 
+but sometimes we can sometimes end up exporting /bin/sh yet use bashisms.
+
+This patch puts bash first in the search results which avoids the bash/dash confusion.
