directly, without consulting $LSHD_CONNECTION in the environment.
$LSHD_LIBEXEC_DIR is consulted later.
(main): Use FILE_LSHD_PTY_HELPER, also without cunsulting environment.
* src/lshd.c (lshd_argp_parser): Analogous change to use
FILE_LSHD_USERAUTH directly.

* src/environ.h.in (ENV_LSHD_CONNECTION): Deleted,
LSHD_LIBEXEC_DIR or service option should be sufficient.
(ENV_LSHD_PTY_HELPER): Likewise.
(ENV_LSHD_USERAUTH): Likewise.
