[BUG] bstrlib.h not put in includes directory from 5.4.0

[connorjward]

Describe the bug
The bstrlib.h file is not put into <prefix>/include for likwid versions 5.4.0+

This is causing pylikwid to not build as it cannot find the bdata macro.

To Reproduce

1. Download and unpack likwid-5.3.0.tar.gz and likwid-5.4.0.tar.gz
2. For each run make && sudo make install (setting the prefix so they install somewhere unique).
3. ls <prefix>/include gives

bstrlib.h  likwid.h  likwid-marker.h

for 5.3.0, but

likwid.h  likwid-marker.h

for 5.4.0. I have verified that this issue persists for 5.4.1 also.

Additional context

Running on Arch Linux

We published a patch for 5.4.0 on the release page (https://github.com/RRZE-HPC/likwid/releases/tag/v5.4.0). It should be fixed in 5.4.1 but, I have to admit, I did not test pylikwid with it.

I'm on vacation and will not be able to fix anything for the next weeks.

But the fix is more likely required on the pylikwid side. It assumes that the affinity group tag is a bstring and thus uses bdata(). This was changed in 5.4+ to be a character array.

Thanks. I have also opened a pylikwid issue discussing this.
