libtomcrypt: add PACKAGECONFIG for ltm enabled by default

Browse Source 
* enabled by default, because that's what dropbear expects and fails
  without as shown in:
  http://errors.yoctoproject.org/Errors/Details/720460/
  dropbear/2022.83-r0/crypto_desc.c:72: undefined reference to `ltm_desc'

* add comment about the LICENSE
* use EXTRA_OEMAKE

* FYI: if you need to use this in dunfell (for whatever reason e.g. to
  avoid CVE-2019-17362 in dropbear which contains bundled libtomcrypt),
  then you need to add:

  # Only needed for dunfell, fixed in kirkstone with:
  # https://git.openembedded.org/openembedded-core/commit/?h=kirkstone&id=4b308773eca7570ce5007e8f953b56252c17fdb1
  DEPENDS += "libtool-cross"
  EXTRA_OEMAKE += "'LIBTOOL=${HOST_SYS}-libtool'"

# Unlicense isn't very accurate for this revision, it was WTFPL in 0.18.0-rc1:
# https://github.com/libtom/libtomcrypt/commit/77e31fb6a980212e90b9a50f116dc5a7bd91e527
# then updated to dual license PD and WTFPL also in 0.18.0-rc1:
# https://github.com/libtom/libtomcrypt/commit/412b2ee1fccc3a0df58f93f372c90d6d0f93bfc9
# and then updated again to Unlicense after the 0.18.2 tag (it's only in develop branch):
# https://github.com/libtom/libtomcrypt/commit/3630bee6fc0f73dd9c7923fd43f8ae15a2c0fb70
# but keep using Unlicense to avoid triggering people with WTFPL license:

# and this comment can be removed next time libtomcrypt is updated
