zoom-us: Link libfaac to fix audio recording (#93374)

Fixes #93341.

Using strace reveals that zoom is attempting to load "libfaac1.so" from
its PATH. As faac provides "libfaac.so.0", solve this by linking from
there to "libfaac1.so" in zoom's output.

This is the same solution as the one we use for libjpeg_turbo.

(cherry picked from commit 903a0ca)
