[lttng-dev] [PATCH lttng-ust] Fix: java class check when uudecode is not present

On systems where 'uudecode' is present, the java class check will
run a precompiled class file in the local directory. If the CLASSPATH
variable doesn't contain "." the test will fail regardless of the
presence of the tested for class on the classpath.

This fix makes the behavior of the test consistant whether 'uudecode'
is present or not.
