gnu: gnushogi: Fix build.

* gnu/packages/games.scm (gnushogi)
[source]: Fix warnings by prefixing "__FUNCTION__" with "__extension__".
[arguments]: Turn off some GCC warnings in C flags.
Set the linker flag to build the program.
Skip the "--enable-fast-install" flag in the configure phase.
Enable the "sizetest" test in the check phase.
[synopsis]: Remove "The" so that the sentence doesn't start with it.
