toaster-manual: Updated the "Installation" to have TOASTER_DIR information

In section 3.6 of the manual about setting up a production instance of
Toaster, explain that TOASTER_DIR determines the location of the build
directory, and that the checksettings command configures the build
environment for Toaster.

NOTE: I applied some minor fixes to the wording.
