[LNT] Fixed cPerf tests
Fixed binary mode for perf files.
Fixed permission denied error while writing test perf files on some systems.
Disabled the test test_random_guff2. It works fine on Windows but causes a Bus Error (SIGBUS) on some Linux systems. It cannot be handled correctly in all cases.
Note we have no fib-aarch64 and fib2-aarch64 binaries to generate the full dump of the symbol table using objdump –t
We have generated fib-aarch64.objdump.out from fib-aarch64.nm.out manually to fix tests.
