Currently a property in the form of
FOO=bar
is stored as " FOO=bar", i.e. the property name contains a leading space.
That's quite hard to spot.
This patch discards all extra whitespaces but the first one which is required
by libudev's hwdb_add_property.
[zj: modify the check a bit]

value++;
+ /* libudev requires properties to start with a space */
+ while (isblank(line[0]) && isblank(line[1]))

if (line[0] == '\0' || value[0] == '\0') {
log_error("Error, empty key or value '%s' in '%s':", line, filename);
return -EINVAL;
