iproute2: tc: reduce size of dynamic symbol table
In the case of SHARED_LIBS=y, don't use -export-dynamic to place *all*
symbols into the dynamic symbol table. Instead, use --dynamic-list to
export a smaller set of symbols similar to that defined in static-syms.h
in the case of SHARED_LIBS=n, avoiding an 11 KB tc package size increase.
Also increment PKG_RELEASE.
