Subject: {linux,bsd}-user: Update ts_tid after fork()
X-Git-Tag: v9.0.0-rc0~32^2~25

{linux,bsd}-user: Update ts_tid after fork()

Currently ts_tid contains the parent tid after fork(), which is not
correct. So far it has not affected anything, but the upcoming
follow-fork-mode child support relies on the correct value, so fix it.
