[PATCH] Parametrize asciidoc and add --unsafe

[Pavel Roskin <proski@gnu.org>]

Including files from the parent directory is considered unsafe by
asciidoc 7.1.0.  This is used in git.txt, which includes ../README.

Since git is developed openly, we shouldn't be afraid of exploits
lurking in the docs.  Create a make variable ASCIIDOC and use it to
always call asciidoc with the --unsafe option.
