zlib: Fix a bug when getting a gzip header extra field with inflate().

If the extra field was larger than the space the user provided with
inflateGetHeader(), and if multiple calls of inflate() delivered
the extra header data, then there could be a buffer overflow of the
provided space. This commit assures that provided space is not
exceeded.

(cherry picked from zlib commit eff308af425b67093bab25f80f1ae950166bece1)
