[9.18] chg: nil: Suppress FreeBSD-specific TSAN false-positive data race

Browse source 
TSAN reports a data race in FreeBSD's memset(), called by its
__crt_calloc() memory allocation function. There is a very similar
bug report [1] in FreeBSD bug tracker, and an existing code-review [2]
that tries to address an issue, the description of which is very
similar to what we are seeing.

Suppress this report by adding its signature to '.tsan-suppress'.

[2] https://reviews.freebsd.org/D28536?id=86694

Closes #5267

Backport of MR !10353

Merge branch 'backport-5267-freebsd-suppress-tsan-data-race-false-positive-9.18' into 'bind-9.18'
