ci: fix deb build script in clean checkout

If ripgrep hasn't been built yet (i.e. target/debug/ doesn't exist),
then cargo-out-dir can't find OUT_DIR and the copy commands fail. Fix by
running cargo build before finding OUT_DIR.

Also add a check to fail early with a sensible error message when
asciidoctor isn't installed, rather than failing because of a missing
rg.1 file after the build.

 # 'cargo deb' does not seem to provide a way to specify an asset that is
 # created at build time, such as ripgrep's man page. To work around this,
 # we force a debug build, copy out the man page (and shell completions)
 # produced from that build, put it into a predictable location and then build
 # the deb, which knows where to look.
