package/pipewire: fix uclibc build

Fix the following uclibc build failure:

/home/buildroot/autobuild/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mipsel-buildroot-linux-uclibc/10.3.0/../../../../mipsel-buildroot-linux-uclibc/bin/ld: src/pipewire/libpipewire-0.3.so.0.351.0.p/introspect.c.o: in function `pw_node_info_merge':
/home/buildroot/autobuild/instance-0/output-1/build/pipewire-0.3.51/build/../src/pipewire/introspect.c:216: undefined reference to `reallocarray'

Fixes:
