Fix cabextract not found in pressure-vessel and TTW game detection

cabextract: The system binary under /usr is invisible inside the
pressure-vessel container where winetricks runs. Always download a
local copy to ~/.local/share/fluorine/bin/ instead of short-circuiting
when the host has it installed.

TTW: The game plugin was calling the base class identifyGamePath()
which tried matching "TTW" against NaK's detected game names — never
matching "Fallout New Vegas". Now explicitly searches for FNV in the
NaK results, mirroring how the Windows path uses the FalloutNV registry
key. Also adds HAS_NAK_FFI and nak_ffi linkage to the TTW CMake target
since it was previously only defined for the game_gamebryo target.
