add -fno-omit-frame-pointer to default complication flags (#12973)

Browse Source 
Currently redis uses O3 level optimization would remove the frame pointer
in the target bin.

In the very old past, when gcc optimized at O1 and above levels, the
frame pointer is deleted by default to improve performance. This saves
the RBP registers and reduces the pop/push instructions. But it makes it
difficult for us to observe the running status of the program. For
example, the perf tool cannot be used effectively, especially the modern
eBPF tools such as bcc/memleak.
