Use ExternalProject for NIH dependencies

Fixes: RIPD-1648

 - use ExternalProject for snappy, lz4, SOCI, and sqlite3
 - use FetchContent for NuDB
 - update SOCI from 79e222e3c2278e6108137a2d26d3689418b37544 to
   3a1f602b3021b925d38828e3ff95f9e7f8887ff7
 - update lz4 from c10863b98e1503af90616ae99725ecd120265dfb to v1.8.2
 - update sqlite3 from 3.21 to 3.24
 - update snappy from b02bfa754ebf27921d8da3bd2517eab445b84ff9 to 1.1.7
 - update NuDB from 00adc6a4f16679a376f40c967f77dfa544c179c1 to 1.0.0

+  This is a function override for one function in the
+  standard ExternalProject module. We want to change
+  the generated build script slightly to include printing
+  the build logs in the case of failure. Those modifications
+  have been made here. This function override could break
+  in the future if the ExternalProject module changes internal
+  function names or changes the way it generates the build
+  scripts.
