tools lib traceevent: Fix python/perf.so compiling error

'make build-test' finds an error that make_python_perf_so fails due to
missing of libtraceevent-dynamic-list:

'.../python2' util/setup.py \
--quiet build_ext; \
mkdir -p python && \
cp python_ext_build/lib/perf.so python/
/path/to/ld: cannot open linker script file /path/to/kernel/tools/lib/traceevent/libtraceevent-dynamic-list: No such file or directory
collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gcc' failed with exit status 1
cp: cannot stat 'python_ext_build/lib/perf.so': No such file or directory
make[3]: *** [python/perf.so] Error 1
make[2]: *** [python/perf.so] Error 2
test: test -f ./python/perf.so
make[1]: *** [make_python_perf_so] Error 1
make: *** [build-test] Error 2
make: Leaving directory `/path/to/kernel/tools/perf'

This is caused by commit e3d09ec8126fe2c9a3ade661e2126e215ca27a80
("tools lib traceevent: Export dynamic symbols used by traceevent
plugins") that, it adds the list file to LDFLAGS but forgot to add it to
dependency list of python/perf.so.

This patch fixes this problem.
