From: Akihiko Odaki <akihiko.odaki@daynix.com>

The arguments in MESONINTROSPECT are quoted with shlex.quote() so it
must be parsed with shlex.split().  Otherwise the script will fail if
the build directory has a character like "~" in it.

Note: this fix cannot be backported directly to any stable branch
that doesn't require Meson version 1.4.0 or better; otherwise it will
work OK on Linux but will break on Windows hosts.

(Unfortunately, Meson prior to version 1.4.0 was inconsistent between
host OSes about how it quoted arguments, and used a different quoting
process on Windows hosts.  Our current git trunk already requires
1.5.0 as of commit 07f0d32641e ("Require meson version 1.5.0"), but
the stable branches are still on older Meson.)

This is essentially back to version 1 of Akihiko's patch, now we
have a new enough Meson; I just updated the commit message.

I confirm this fixes the error when the path to qemu src tree contains '~'.

I confirm this fixes the problem we detected in our CI (where some build
dirnames have '~'
