swr: don't forget to link AVX/AVX2 against pthreads

Seems like the backends have been using pthreads since day one, yet
we've been missing the link.

With later commit we'll fix a typo, hence the libraries will be build
with -Wl,no-undefined, aka failing the build on unresolved symbols.

v2: Split from a larger patch.
