Add support for building the project with meson.
As libtracecmd lives in the same source tree as trace-cmd, we have
to place the 'top' meson.builld file under lib but we can't reference
it from the root meson.build which controlling the main trace-cmd
build.
This implies we can't access resources/path which are not below the
library's main meson.build directly. Thus, to be able to build the
documentation we have to use the symlink as workaround.

Add support for building the project with meson.
trace-cmd depends on a statically linked libtracecmd
(e.g. trace_perf_open, trace_perf_close, trace_perf_init).
Instead depending libtracecmd to be compiled and installed
separately add libtracecmd directly to trace-cmd build. This
avoids an additional step.
We still are able to build libtracecmd as stand alone project.
The top meson.build file just lives in the lib directory.
