tools/perf: Use is_perf_pid_map_name helper function to check dso's of pattern /tmp/perf-%d.map

commit 80d496be ("perf report: Add support for profiling JIT
generated code") added support for profiling JIT generated code.
This patch handles dso's of form "/tmp/perf-$PID.map".

Some of the references doesn't check exactly for same pattern.
some uses "if (!strncmp(dso_name, "/tmp/perf-", 10))". Fix
this by using helper function perf_pid_map_tid and
is_perf_pid_map_name which looks for proper pattern of
form: "/tmp/perf-$PID.map" for these checks.
