btrfs-progs: build: use thread-safe profile generation flags

Browse source 
The CI lcov generation fails due to:

Processing ./common/device-utils.gcda
geninfo: ERROR: Unexpected negative count '-6' for /home/runner/work/btrfs-progs/btrfs-progs/common/device-utils.h:69.
	Perhaps you need to compile with '-fprofile-update=atomic
	(use "geninfo --ignore-errors negative ..." to bypass this error)

Use a safer way to gather the profile stats.
