[PATCH v5 23/24] test/atomic: suppress deprecation warnings for legacy APIs

[Stephen Hemminger <stephen@networkplumber.org>]

The rte_atomicNN_* APIs are now marked __rte_deprecated.
Wrap the whole file with __rte_diagnostic_push / pop and a
GCC pragma -Wdeprecated-declarations.

In future, when the APIs are removed this test collapses to just the
128-bit compare-and-swap case and the suppression goes with it.
