Make unix (local) sockets work without IPv6 enabled

The xsocket_type() function had an optional "family" argument
that was enabled only if IPv6 is enabled. In the case of the
function was called with a valid AF_UNIX argument, and IPv6 is
disabled, this argument was silently ignored.

This patch makes the "family" argument mandatory, while keeping
the old behavior i.e., if AF_UNSPEC is passed, we try first IPv6
(if it's enabled) and fallback to IPv4.

Also I changed all callers of xsocket_type() to reflect its new
interface.

gen_build_files.sh: exclude hidden directories

I am using quilt to manage patches internally. Quilt creates dir .pc
and stores unmodified files there. Since I made change in one of
Config.src quilt made a copy in .pc/xxx.patch/xxx/Config.src. When
I run make it calls gen_build_files.sh and it generates
.pc/xxx.patch/xxx/Config.in. Now when I want to pop patch quilt
thinks I have made changes to original xxx/Config.in.

IMO the best solution is just to ignore hidden directories in
gen_build_files.sh. This also results in shorter build time in case
busybox is under git/svn versioning, since it avoids searching
many directories for Config.src.
