minilzo: Update to minilzo-2.10

minilzo fails to build on a number of Debian release architectures
(armel, mips64el, mipsel, ppc64el) with errors such as:

  ../../grub-core/lib/minilzo/minilzo.c: In function 'lzo_memops_get_le16':
  ../../grub-core/lib/minilzo/minilzo.c:3479:11: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
   3479 |         * (lzo_memops_TU2p) (lzo_memops_TU0p) (dd) = * (const lzo_memops_TU2p) (const lzo_memops_TU0p) (ss); \
        |           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  ../../grub-core/lib/minilzo/minilzo.c:3530:5: note: in expansion of macro 'LZO_MEMOPS_COPY2'
   3530 |     LZO_MEMOPS_COPY2(&v, ss);
        |     ^~~~~~~~~~~~~~~~

The latest upstream version is 2.10, so updating to it seems like a good
idea on general principles, and it fixes builds on all the above
architectures.

The update procedure documented in the GRUB Developers Manual worked; I
just updated the version numbers to make it clear that it's been
executed recently.
