build: create .o files specifically for java-related targets 

Summary:
When building rocksdbjava and rocksdbjavastatic, create -fPIC-enabled
binaries in a temporary subdirectory, jl/.
* Makefile (java_libobjects): New variable.
(java_libobjects): New rule.
(CLEAN_FILES): Arrange for "make clean" to remove that temporary dir.
(rocksdbjavastatic): Depend on the new variable.
Remove useless OPT=... line.
(rocksdbjava): Likewise.

Test Plan:
  JAVA_HOME=/usr/local/jdk-7u67-64 PATH=$JAVA_HOME/bin:$PATH \
    make rocksdbjavastatic
