Copy .git to build place

[wingedfox]

Hi,

Builder image is incompatible with gradle plugin com.gorylenko.gradle-git-properties because it does not copy .git to a build directory.
The issue us caused by using * wildcard:

s2i-java/sti/bin/assemble

Line 18 in 221c47a

cp -ad /tmp/src/* $LOCAL_SOURCE_DIR

This could be solved by either using cp -rad /tmp/src/ $LOCAL_SOURCE_DIR or removing entire block as stated in TODO above.
