package/mariadb: explicitly disable the column store plugin

Building the column store plugin (which gets automatically enabled
when Boost with a bunch of submodules is found) currently fails as it
requires a number of runtime checks that obviously cannot work when
cross-compiling.

OpenEmbedded has defined them as such:

  -DLSTAT_FOLLOWS_SLASHED_SYMLINK_EXITCODE=0 \
  -DSTAT_EMPTY_STRING_BUG_EXITCODE=0 \
  -DMASK_LONGDOUBLE_EXITCODE=0 \

but it really isn't clear whether those values are completely correct
for all CPU architectures, especially the last one.

So instead, let's disable the column store plugin until someone
actually needs it and figures out how to set those variables properly.

The issue fixed by this commit can be reproduced using the following
defconfig:

BR2_aarch64=y
BR2_ARM_FPU_VFPV3D16=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_PACKAGE_MARIADB=y
BR2_PACKAGE_MARIADB_SERVER=y
BR2_PACKAGE_BOOST=y
BR2_PACKAGE_BOOST_DATE_TIME=y
BR2_PACKAGE_BOOST_FILESYSTEM=y
BR2_PACKAGE_BOOST_REGEX=y
BR2_PACKAGE_BOOST_THREAD=y
