scd,tpm2d: Fix for consistent use of socket FD.
* scd/command.c (scd_command_handler): Use gnupg_fd_t for the argument but no INT2FD to listen. Use GNUPG_INVALID_FD. * tpm2d/command.c (tpm2d_command_handler): Likewise. * scd/scdaemon.c (start_connection_thread): Follow the change. * tpm2d/tpm2daemon.c (start_connection_thread): Likewise. * scd/scdaemon.h (scd_command_handler): Use gnupg_fd_t. * tpm2d/tpm2daemon.h (tpm2d_command_handler): Likewise.
