[LTP] [PATCH v2 2/3] lib: Rename variable LTP_ENABLE_DEBUG => LTP_DEBUG

[Petr Vorel]

1) LTP_DEBUG is shorter to write.
2) Enable is usually meant as boolean (on/off), that hides possible 2
value even more.

 The LTP framework supports ``TDEBUG`` flag test debug messages. These
-messages can be enabled using the ``-D[1,2]`` parameter or setting ``LTP_ENABLE_DEBUG=1,2``

 The ``-D`` parameter also supports the following verbosity levels:
