Add a defines.mk file defining the standard default layout
for installation (PREFIX, DATAROOTDIR, LIBDIR etc.).
Add a $(JSDIR) variable and use env!("JSDIR") in place of
the hardcoded /usr/share/javascript/proxmox-backup path.
Have defines.mk include an *optional* local.mak to override
JSDIR to www/ during local development.
Add `make install` targets and remove debian/install.
Note that service files are now in $libdir/proxmox-backup/
as there's usually no point in starting them from the
command line, so /usr/sbin makes no sense.

We want to run the public server as user www-data. Requests needing
root priviledges needs to be proxied to the proxmox-backup.service, which
now listens to 127.0.0.1:82.
