Build tagsoup with sdk_version := "core_current"

The tagsoup is using only core API. But it is defined java:platform
which can use internal API, since tagsoup is not defined sdk_version.
So, sdk_version := "core_current" is added in tagsoup, because it can be
turn into errors when link type check becomes more strict.

Test: mma -j under tagsoup dir
