This will allow systemtap to pass options to bminstall. This can include
an option such as -Jorg.jboss.byteman.compile.to.bytecode which will then
be passed as -Dorg.jboss.byteman.compile.to.bytecode and directly compile
the byteman rule to bytecode, allowing for faster rule execution
*cmdline.h: add the J case
*java/stapbm: add the new (optional) parameter to be passed
*session.cxx: add the new -J case statement
*session.h: compilation variable
*tapset-method.cxx: append the passed command
