    Fix all PATH problems in testsuite/gdb.perf/
    
    Currently "make check-perf" triggers ~40 PATH messages in gdb.sum:
    
      ...
      PATH: gdb.perf/backtrace.exp: python sys.path.insert(0, os.path.abspath("/home/pedro/rocm/gdb/build/gdb/../../src/gdb/testsuite/gdb.perf/lib"))
      PATH: gdb.perf/backtrace.exp: python exec (open ('/home/pedro/rocm/gdb/build/gdb/testsuite/outputs/gdb.perf/backtrace/backtrace.py').read ())
      ...
    
    This commit fixes them.  E.g. before/after gdb.sum diff:
    
     -PASS: gdb.perf/backtrace.exp: python import os, sys
     -PASS: gdb.perf/backtrace.exp: python sys.path.insert(0, os.path.abspath("/home/pedro/rocm/gdb/build-master/gdb/../../src/gdb/testsuite/gdb.perf/lib"))
     -PATH: gdb.perf/backtrace.exp: python sys.path.insert(0, os.path.abspath("/home/pedro/rocm/gdb/build-master/gdb/../../src/gdb/testsuite/gdb.perf/lib"))
     -PASS: gdb.perf/backtrace.exp: python exec (open ('/home/pedro/rocm/gdb/build-master/gdb/testsuite/outputs/gdb.perf/backtrace/backtrace.py').read ())
     -PATH: gdb.perf/backtrace.exp: python exec (open ('/home/pedro/rocm/gdb/build-master/gdb/testsuite/outputs/gdb.perf/backtrace/backtrace.py').read ())
     +PASS: gdb.perf/backtrace.exp: setup perftest: python import os, sys
     +PASS: gdb.perf/backtrace.exp: setup perftest: python sys.path.insert(0, os.path.abspath("${srcdir}/gdb.perf/lib"))
     +PASS: gdb.perf/backtrace.exp: setup perftest: python exec (open ('${srcdir}/gdb.perf/backtrace.py').read ())

            * lib/perftest.exp (PerfTest::_setup_perftest): Use
            with_test_prefix.  Add explicit test names to python invocations,
            with "$srcdir" not expanded.
