Fix deprecation warnings in latest fedora rawhide

google/heap-profiler.h and google/malloc_extension.h were deprecated in favor of gperftools/heap-profiler.h and gperftools/malloc_extension.h, this prints a warning in latest fedora, the patch changes the includes to fix the warning
Fix -Wno-format and -Werror=format-security options clash

This causes build failure in latest fedora builds, ceph_test_librbd_fsx adds -Wno-format cflag but the default AM_CFLAGS already contain -Werror=format-security, in previous releases, this was tolerated but in the latest fedora rawhide it no longer is, ceph_test_librbd_fsx builds fine without -Wno-format on x86_64 so there is likely no need for the flag anymore
