nginx: fix nginx lua module compilation error

Add pending patch fixing compilation error for missing pcre.h.

This is caused by a bug on their end by trying to add pcre.h even if we
are using the PCRE2 library.

+Subject: [PATCH] bugfix: don't include pcre.h with PCRE2 used
+
+pcre.h is a PCRE header and is not exposed by PCRE2 library causing
+compilation error as the header is not found.
+
+Don't include pcre.h if nginx is compiled with PCRE2 support enabled.
