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] https://bugs.freedesktop.org/show_bug.cgi?id=82311
