Description

The linux-gate handling has been kind of broken in LinuxDumper for a while,
probably since I changed how File IDs were generated. Since it's not a physical
file on disk, the existing File ID generation fails. This patch causes us to
special-case it so we get a valid File ID out of it. I would guess that the
linux-gate symbol files in the tree need to be updated as well, since they will
probably have different IDs, but I only currently have a 64-bit Linux, so I'm
not 100% sure of the process to regenerate them.

LGTM
Yeah, updating the symbol files should be an easier-to-repeat process.  IIRC
every process on a system will have the same linux-gate mapped but I wonder if
the mapping for the VDSO itself has even changed in recent versions of Linux.
