Allow user space file locations (rootless support)

Why:
Running dropbear as a user (rootless) is aided if
files and programs can be saved/removed without
needing sudo.

What:
Use the same convention as DROPBEAR_DEFAULT_CLI_AUTHKEY;
if not starting with '/', then is relative to hedge's /home/hedge:
*_PRIV_FILENAME
DROPBEAR_PIDFILE
SFTPSERVER_PATH

default_options.h commentary added.

Changes kept to a minimum, so log entry in svr_kex.c#163
is refactored.
From:
    Generated hostkey is <path> ... <finger-print>
to:
    Generated hostkey path is <path>
    Generated hostkey fingerprint is <fp>
Otherwise the unexpanded path was reported.
