nginx-devel: updated to 1.13.8

Changes with nginx 1.13.8:

*) Feature: now nginx automatically preserves the CAP_NET_RAW capability
   in worker processes when using the "transparent" parameter of the
   "proxy_bind", "fastcgi_bind", "memcached_bind", \ 
"scgi_bind", and
   "uwsgi_bind" directives.

*) Feature: improved CPU cache line size detection.
   Thanks to Debayan Ghosh.

*) Feature: new directives in vim syntax highlighting scripts.
   Thanks to Gena Makhomed.

*) Bugfix: binary upgrade refused to work if nginx was re-parented to a
   process with PID different from 1 after its parent process has
   finished.

*) Bugfix: the ngx_http_autoindex_module incorrectly handled requests
   with bodies.

*) Bugfix: in the "proxy_limit_rate" directive when used with the
   "keepalive" directive.

*) Bugfix: some parts of a response might be buffered when using
   "proxy_buffering off" if the client connection used SSL.
   Thanks to Patryk Lesiewicz.

*) Bugfix: in the "proxy_cache_background_update" directive.

*) Bugfix: it was not possible to start a parameter with a variable in
   the "${name}" form with the name in curly brackets without enclosing
   the parameter into single or double quotes.
