Fix gcc10.1 truncation error
gcc10.1 complains with:
../../include/sys/dmu.h:373:24: error: ‘%s’ directive output may be
truncated writing up to 95 bytes into a region of size 75
[-Werror=format-truncation=]

../../module/zfs/ddt.c:256:37: note: in expansion of macro
‘DMU_POOL_DDT’

| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Increasing DTT_NAMELEN fixes it.
