nginx: new package

Add nginx package. Heavily inspired by Buildroot's nginx.mk, using their
revised patches for 1.10.x and the endian patch from Marc Kleine-Budde,
as well as the nginx.make from the patchset Robert sent, as a starting
point.

But instead of building the modules by default, each module is
selectable in PTXdist, to allow reducing the binary size.

Most popular modules are supported, systemd unit file and basic
configuration files are included as well.
Supports SSL, HTTP/2, HTTP Proxying, GZIP, Auth Basic, Rewrite, FastCGI,
SCGI, uWSGI, etc.
