Relax ttyname_r error checks
* src/engine-assuan.c (llass_new): Don't treat ttyname_r error as
fatal.
* src/engine-g13.c (g13_new): Likewise.
* src/engine-gpg.c (gpg_new): Likewise.
* src/engine-gpgsm.c (gpgsm_new): Likewise.
* src/engine-uiserver.c (uiserver_new): Likewise.

Even though isatty() returns 1, ttyname_r() may fail in many ways, e.g.,
when /dev/pts is not accessible under chroot. Since all our uses of
ttyname_r() require that the function works, we can treat the failure as
if isatty() fails.
