You can increase it if you really have to by building the latest version of Squid (3.4.7 or later anyway) using:
  ./configure CXXFLAGS="-DMAXTCPLISTENPORTS=256"

 or whichever number you want to increase it to.

For each packet read Squid has to check the listening port list to see if it is a read() or accept() operation. Doing even 128 checks per packet is pushing the boundaries for reasonable performance loss.
