lib/raid6/test: fix multiple definition linking error
GCC 10+ defaults to -fno-common, which enforces proper declaration of external references using "extern". without this change a link would fail with: lib/raid6/test/algos.c:28: multiple definition of `raid6_call'; lib/raid6/test/test.c:22: first defined here the pq.h header that is included already includes an extern declaration so we can just remove the redundant one here.
