Keep linux binaries names short

[miry]

Closes #330

Linux packages installs binaries to /usr/local/bin
and has names:

toxiproxy-server-linux-amd64
toxiproxy-cli-linux-amd64

It is not common way and different from previous releases.

Changes the binary destination path to /usr/bin and has short binary
names:

toxiproxy-server
toxiproxy-cli

Verification:

make
