Make DB and ISCSIHOME directories configurable.

This commit adds two new top-level build options: one
for the "home" directory for open-iscsi called "HOMEDIR",
and one for the "database" directory, called "DBROOT". One can
now override the defaults of "/etc/iscsi" for either or
both of these directories on the make command line.
The README and man pages are updated with details about
these new options.

Some Makefile cleanup/repair was done as well. Installation
of the initiatorname.iscsi file, was moved out of the top-level
Makefile into the etc subdirectory, and installation of man
ages moved from the top-level Makefile to the doc subdirectory.

Also, this fixes some issues from commit fd14dd8316b1 ("Clean
p Makefile build system."), which incorrectly changed the DESTDIR
ariable in the Makefiles. This current commit also fixes the
top-level variable names for moving DBROOT and HOMEDIR.
