gdbsupport: re-indent ptrace.m4

For some reason, autoupdate isn't able to grok ptrace.m4:

    $ autoupdate ptrace.m4
    /usr/bin/m4:/tmp/auYjuodw/input.m4:171: ERROR: end of file in string
    autoupdate: /usr/bin/m4 failed with exit status: 1

Honestly, I'm unable to grok it either.  This patch re-indents it in a
way that I think is easier to read.  With this patch applied, autoupdate
becomes able to parse ptrace.m4, but I chose to keep this re-indent in a
patch of its own.

All the changes in generated configure files consist of insignificant
whitespace changes.
