app/compress-perf: fix out-of-bounds read

One issue caught by Coverity 344984
*overrun-local: Overrunning array cperf_test_type_strs of 2 8-byte elements

The array cperf_test_type_strs defined in app/test-compress-perf conflicts
with the same name being defined in app/test-crypto-perf. Due to which
coverity reports error.

The fix is to rename "cperf_test_type_strs" into "comp_perf_test_type_strs"
in app/test-compress-perf to avoid name confusion.

Fixes: 1a9b0f3504 ("app/compress-perf: add --ptest option")
