Normalize include guards in gdb

While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards.  I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.

So, I changed the script to normalize all include guards in gdb.  This
patch is the result.

As usual the script is available here:

    https://github.com/tromey/gdb-refactoring-scripts

Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.
