Subject: [PATCH] libpqxx: apply upstream compilation fix

Apply an upstream patch which addresses a compilation issue with respect
to an undefined 'timeval' structure. This issue exists in at least v6.0.
It is expected that this patch can be removed when libpqxx provides a
new releases (either v6.0.1 or v6.1).

Fixes:

+Subject: [PATCH] include sys/time.h outside fallback select (#55)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The implementation of 'wait_fd' (inside 'connection_base.cxx') always
+relies on the existence of the 'timeval' structure. In Linux, this
+structure is provided by the header 'sys/time.h'. If polling or select
+capabilities are detected, the structure is never included into the
+source and will result in a compilation error (GCC 7.x):
+
+    connection_base.cxx:1153:28: error: ‘{anonymous}::tv_milliseconds’ declared as an ‘inline’ variable
+     inline int tv_milliseconds(timeval *tv = nullptr)
+                                ^~~~~~~
+    ...
+
+The following moves the 'HAVE_SYS_TIME_H' check outside the
+select-fallback case so that the header can be included no matter the
+event-function feature is used.
