Extract: Parse Unicode Path Extra field in minizip

Adds parsing of the Info-ZIP Extra field which overrides the
file name in the File Header only if the CRC in the extra field
is a CRC of the file name in the File Header.

See https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT
section 4.6.9 for reference.

Also tidied up some whitespace indent.
