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

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.
