Remove setting Make SHELL completely from the build system

...this is a follow-up to efad388f75 "Clean up
Make SHELL handling," which broke out-of-tree builds.

There appears to be no good reason at all to fiddle with Make's own behavior of
determining its SHELL variable (which defaults to /bin/sh and can be overridden
via a SHELL=... command line argument when invoking Make).  The SHELL_BASH
fiddling in configure.ac and Makefile.in was probably cargo cult carried along
ever since 815f157c05 "CWS-TOOLING: integrate CWS
configuretoplevel," in a time when the OOo build system still defaulted to tcsh.
