fix: allow to termStatusReport on a PTY

[caarlos0]

A pty is not in foreground, but it can do the IOCTL ops we need.

My understanding might be wrong, but I think that if the term cannot do the TCGETS it will fail the same way it would when checking if its in foreground, so maybe that check is even needed?
