fixup! Win32: implement basic symlink() functionality (file symlinks only)

This patch fixes signature of the CreateSymbolicLinkW() function's
declaratoin. The previous declaration claimed that said function returns
a BOOL, while it really returns a BOOLEAN.

This is not an academic distinction: BOOL is defined as an int (i.e.
32-bit) and BOOLEAN as an unsigned char (i.e. 8-bit). Therefore, the
return value 0 (meaning, the least-significant 8 bits are all zero)
could be mistaken to indicate a successful creation of the symbolic
link (because the remaining 24 bits are undefined, and quite likely
non-zero).
