Modernize INSTALL a bit

Browse source 
* INSTALL: Omit filesystem space estimates.  These estimates
were (1) wrong and (2) no longer important nowadays, as people
have plenty of space.  Instead, start with how to get and
unpack an Emacs tarball.  Don’t say "disk" as it’s often not
disk nowadays.  Update URLs.

The final installed Emacs uses about 150 MB of disk space.
This includes the space-saving that comes from automatically
compressing the Lisp source files on installation.
