lzmainfo: Open named files in binary mode

Browse Source 
On native Windows, lzmainfo opened named .lzma files in text mode while
stdin was already binary. The C runtime treats 0x1A as EOF and translates
CRLF in the 13-byte header. A valid file with a known uncompressed size
of 26 bytes failed with "File is too small to be a .lzma file"; a known
size of 2573 bytes was incorrectly reported as 10 bytes. Reading the same
files through stdin or - reported the correct sizes.
