package/ltp-testsuite: refine architecture dependency

As stated in commit [1], sparc toolchains doesn't have
any of __sync_*() family of functions implementation.

When __sync_add_and_fetch() is missing, ltp fallback to a local
implementation of tst_atomic_add_return() specific for each
supported architecture.
But there is none for sparc.

So add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 except for
architectures where a specific implementation is provided
in ltp-testsuite.

Fixes:
