[gh actions] Enable LSAN leak detection when running CI

[chantra]

Once https://github.com/iovisor/bcc/pull/4127 lands, the test suite should be able to run leak free. Enabling the LeakSanitizer will help preventing leaks being introduced in the future.

This diff makes leak sanitization the default for all our tests running in CI.

I will need to re-base this on https://github.com/iovisor/bcc/pull/4127 once it is landed to make sure it is not triggering any other errors.

We have a test failure with missing lsan library,

[  7%] Building C object src/cc/CMakeFiles/bpf-shared.dir/libbpf/src/bpf.c.o

So, this is happening on fedora, it probably just need to be installed a new library.

Also, cmake in bionic is at version 3.10, but add_link_options was added in 3.13

Ok. With those 2 other patches. Failures are now isolated to the test runs, which I believed failed before.

I am putting this one on hold for now. Python and LSAN are not good friends: https://tobywf.com/2021/02/python-ext-asan/

I need to find a way to disable LSAN just in the context of python runs before this can be enabled.
