sox: backport fix for dynamically linked flac builds

The sox project upstream is dead, non-responsive, and various
developers started maintaining their own branches where they do
feature development (eg. adding DSD/DSF format support) and
bug-fixing. They don't have access to the central sox git repo.

So basically the project will eventually get forked (I started a
discussion in this direction). Until then, backport this flac build
fix which was lingering around out of tree for years.

+Subject: [PATCH] Update exported symbol list
+
+commit 5c58413544 ("Don't export (most) internal libsox symbols")
+breaks dynamic flac builds as flac.c references lsx.error, so add it
+to the list of exceptions.
+
+| .libs/flac.o: In function `decoder_read_callback':
+| /usr/src/debug/sox/14.4.2-r0/sox-14.4.2/src/flac.c:63: undefined reference to `lsx_error'
