Scott James Remnant chased this up.  'blkid -o list' shows mount points,
but this is implemented in the blkid command-line tool rather than in
the libblkid library.  I don't think it would be significantly easier
for grub-probe to parse the output of a command-line tool than for it to
just parse /proc/self/mountinfo, and it certainly wouldn't be any
quicker, so I suggest staying with the approach in my branch until some
appropriate feature is available in libblkid or another common library.
