scst: fix memory leak in scst_proc_group_add()
Valgrind noticed that the "name" allocated in scst_proc_group_add() was
leaking. It turns out that scst_alloc_add_acg makes its own copy of the name
passed to it from this code, making the string duplication done here redundant
(and leaky). The change eliminates the string duplication (along with all its
associated error handling logic) and simply passes the (unowned) incoming
string down for duplication below.

Not all SCST components handle DESTDIR properly, or at all.
In particular:
* INSTALL_MOD_PATH should account for DESTDIR when 'make modules_install'
is invoked, so the kernel make infrastructure deploys the modules
and runs depmod against the proper directory tree.
* depmods must include a '-b' option to reference the proper directory tree.
* Drop special ISCSI_DESTDIR.

Currently the install location of SCST is pretty much hard coded into
the Makefiles to be /usr/local.
I am custom building a system for ZFS & SCST and I want to install in
/usr instead of /usr/local.
Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.
This patch fixes it.
