Fixed segfault on ubuntu by updating apr

[gaby64]

included your changes to apr in the update

I can confirm, on MacOS (Catalina) there was a segfault also, when trying to run app after build. This gaby64's changes fixed this.
By the way, I also needed to give exact zlib path to configure. Otherwise it gave me "not found" error.
(i.e. ./configure --prefix=/usr/local/apache2nginx --with-z=/usr/local/Cellar/zlib/1.2.11)

Unfortunately, this does not appear to work on Ubuntu 18.04.4 LTS:

@gaby64 Could you maybe make a Docker version of this app? :)

sudo apt install libexpat1
