[pushed] testsuite: Import objc-dg-prune in execute.exp

[Richard Sandiford via Gcc-patches]

The GCC-local definition of gcc-dg-prune removes extra error messages,
such as one from the linker warning about executable stacks.  This is
then used by tool-specific pruners like objc-dg-prune, defined in
objc-dg.exp.  However, objc/execute/execute.exp didn't include
objc-dg.exp, meaning that the linker warning could trigger a
failure in objc/execute/nested-func-1.m.

Tested on aarch64-linux-gnu & x86_64-linux-gnu, pushed as obvious.
