[PATCH v2 3/5] meson: add docdir option and pass pre-prefix qemu_docdir

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

When cross-compiling, by default qemu_docdir is 'c:\Program Files\QEMU\'
which is not recognized as being an absolute path, and meson will end up
adding the prefix again.

Add an option to pass docdir location to meson, pre-prefixed like we do
with other directories and use that instead of config_host['qemu_docdir'].
