udevadm hwdb: discard extra leading whitespaces in hwdb
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]
