package/mtd: select BR2_PACKAGE_LIBOPENSSL_ENGINES

mtd ubifs unconditionally calls the (deprecated) ENGINE_* logic in
libopenssl resulting in a build failure when
!BR2_PACKAGE_LIBOPENSSL_ENGINES since commit
623d3bbe43e9193aa8e3395367d01af59071b859:

  CCLD     mkfs.ubifs
/home/autobuild/autobuild/instance-1/output-1/host/lib/gcc/powerpc64-buildroot-linux-gnu/13.3.0/../../../../powerpc64-buildroot-linux-gnu/bin/ld: ubifs-utils/mkfs.ubifs/mkfs_ubifs-sign.o: in function `sign_superblock_node':
sign.c:(.text+0x328): undefined reference to `ENGINE_load_builtin_engines'
