pgo: explicitly set LLVM_PROFILE_FILE envvar

Browse source 
When building foot with pgo under gentoo's portage, LLVM tried to
generate profile data files directly under system root, triggering
sandbox violation and causing build to fail. Setting this envvar fixes
the issue by explicitly specifying profiling data location.
