Dropbear 0.49pre1 build error on non-PAM systems

[Federico Bianchi]

Should it matter, Dropbear 0.49pre1 fails to build on a Linux/uClibc if
PAM support is disabled (as I do for fail-safe purposes). The workaround
is extremely simple: the line

	#ifdef ENABLE_SVR_PAM_AUTH

in svr-authpam.c must be placed _before_ the #include (or everything else,
for that matter).
