IMPORTANT: reproduce/software/bash renamed to reproduce/software/shell

Until now the shell scripts in the software building phase were in the
`reproduce/software/bash' directory. But given our recent change to a
POSIX-only start, the `configure.sh' shell script (which is the main
component of this directory) is no longer written with Bash.

With this commit, to fix that problem, that directory's name has been
changed to `reproduce/software/shell'.

+# WARNING:
+#
+# If the commit is aborted (e.g. by not entering any synopsis),
+# then updated metastore file (.metadata by default) is not reverted,
+# so its new version remains in the index.
+# To undo any changes in metastore file written since HEAD commit,
+# you may want to reset and checkout HEAD version of the file:
+#
+#     git reset HEAD -- .metadata
+#     git checkout HEAD -- .metadata
+#
+# This script is taken from the `examples/hooks/pre-commit' file of the

+# for copyright). Here, the name of the `MSFILE' and also set special
+# characters for the installation location of meta-store so our own
