Confusing docs around PREFIX

[edbaunton]

The documentation specifies that /usr/local will be used as the PREFIX if PREFIX is not set.

But I don't see any evidence of that being the case. The Makefile specifies: bldroot as the prefix.

The readme also says:

This tool will check for the config file in two places:

• $(PREFIX)/etc/userchroot.conf
• /etc/userchroot.conf

But in reality only checks for ${PREFIX}/etc/userchroot.conf, which amusingly is also affected by the above, which changes the advertised default to /bldroot/etc/userchroot.conf.
