Terraria: Convert CentOS-based image to Alpine

[geoffmore]

This requires examination of the libraries on both systems. I probably need tools that show me the libraries a binary tries to load.

After adding

libgcc
libc6-compat

to the alpine image, I still get the error
Error relocating TerrariaServer.bin.x86_64: __isnanf: symbol not found Error relocating TerrariaServer.bin.x86_64: backtrace: symbol not found Error relocating TerrariaServer.bin.x86_64: __finite: symbol not found Error relocating TerrariaServer.bin.x86_64: backtrace_symbols: symbol not found Error relocating TerrariaServer.bin.x86_64: __isnan: symbol not found Error relocating TerrariaServer.bin.x86_64: __isinf: symbol not found
This may be related to gliderlabs/docker-alpine#149, in which case there may not be a simple solution for this (unless I recompile the binary)
