coregrind/m_debuginfo/readpdb.c (DEBUG_SnarfLinetab): Remove this_seg

GCC notices that this_seg is set, but never really used in this
function

m_debuginfo/readpdb.c: In function 'DEBUG_SnarfLinetab':
m_debuginfo/readpdb.c:1542:23: warning: variable 'this_seg' set but not used [-Wunused-but-set-variable=]
 1542 |    Int                this_seg;
      |                       ^~~~~~~~

Fix this by just removing this_seg.
