dropbear: deterministic selection of system -vs- bundled libtom libs

Dropbear will use system versions of libtommath and libtomcrypt if
available. To make builds deterministic, add a PACKAGECONFIG option
to choose system libs or force use of the bundled versions.

Note that currently there are no libtommath or libtomcrypt recipes
in oe-core, so default to using the bundled versions.
