[PATCH] fix the mistake of swapping function parameters of read_proc_environ_var

_is_osbuild fails because it expects the 1st and 2nd function parameter to be the environment variable and environ file path respectively. Fix it by swapping the parameters in read_proc_environ_var. Note the osbuild environ file path is defined in _OSBUILD_ENVIRON_PATH so _is_osbuild can be unit-tested by overwriting _OSBUILD_ENVIRON_PATH.
