[PATCH] Quote ' as \(aq in manpages

[Thomas Rast <trast@student.ethz.ch>]

The docbook/xmlto toolchain insists on quoting ' as \'.  This does
achieve the quoting goal, but modern 'man' implementations turn the
apostrophe into a unicode "proper" apostrophe (given the right
circumstances), breaking code examples in many of our manpages.

Quote them as \(aq instead, which is an "apostrophe quote" as per the
groff_char manpage.

I've had this around since my last rant, and it actually gives good
results with both setups I can test on, which are:

- asciidoc 8.4.5, docbook-xsl 1.75.2, xmlto 0.0.18
- asciidoc 8.2.7, docbook-xsl 1.73.2, xmlto 0.0.20
