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.
