[PATCH v3 22/33] doc/scripts/hxtool.py: Strip trailing ':' from DEFHEADING/ARCHHEADING

[Peter Maydell]

In hxtool files, section headings defined with the DEFHEADING
and ARCHHEADING macros have a trailing ':'
  DEFHEADING(Standard options:)

This is for the benefit of the --help output. For consistency
with the rest of the rST documentation, strip any trailing ':'
when we construct headings with the Sphinx hxtool extension.
This makes the table of contents look neater.

This only affects generation of documentation from qemu-options.hx,
which we will start doing in a later commit.
