perf build: Don't always set -funwind-tables and -ggdb3
Commit 6a40cd90f5
("perf tools: Add libunwind dependency for DWARF
CFI unwinding") added libunwind support but also -funwind-tables and
-ggdb3 to the standard build. These build flags aren't necessary so
remove, set -g when DEBUG is enabled for the build.
