LOG: [lldb/test] Replace gnu-style-compression.cpp with a yaml file

In D117744, llvm removed writing support for this format, breaking the
test. We may eventually want to remove reading support as well, but for
now I have converted the test to a yaml file to maintain coverage.

Added: 
    lldb/test/Shell/SymbolFile/DWARF/x86/gnu-style-compression.yaml

Modified: 
    

Removed: 
    lldb/test/Shell/SymbolFile/DWARF/x86/gnu-style-compression.cpp
