package/trace-cmd: bump to version 2.9.1

The layout of the pacakge direcotry has changed, as upstream has added
more than just trace-cmd in the repository (e.g. kernel-shark).

However, the buildsystem for trace-cmd is... unconventional:

  - the top-level Makefile will recurse into the trace-cmd/
    sub-directory, but does not pass any variable on the $(MAKE) command
    line; instead, it exports them in the environment, e.g.:
        export CFLAGS

  - the top-level Makefile appends some definitions to CFLAGS et al.,
    sometimes with a simple append-assignment, sometimes with an
    overriden append-assignment, e.g.:
        CFLAGS += -DVSOCK
        override CFLAGS += -DNO_PTRACE

  - the top-level Makefile does not export all the variables. For
    example, LDFLAGS is not exported;

  - the Makefile in the trace-cmd/ sub-directory expects some variables
    to be set, which is done by the top-level Makefile.

As a consequence, we can no longer pass our variable definitions as make
variable defintions on the command line; we must pass them in the
environment. Note that for some, like CFLAGS, that would still work, but
it would not for others, like LDFLAGS; for consistency, we put all in
the environment.

We can however use the provided 'make install', that behaves as
expected. But we must repeat most environment variables; especially, we
duplicate TARGET_CONFIGURE_OPTS as it has PATH et al. which are needed
by the top-level Makefile to properly detect tools (e.g. swig), which it
uses to decide what it should install.

Drop upstreamed patch.

Update the licensing information: new license files have been added in a
sub-directory, and the top-level COPYING now only references those two
(rather than being the actual text of the GPL-2).

Use two spaces in hash file.

[yann.morin.1998@free.fr:
  - keep using a git clone
  - unbreak the build:
    - use the default make target rule, or the plugins and python
      bindings be built at install time, with the host compiler
    - use the default install target rule
  - expand commit log:
    - detail buildsystem issues
  - add new license files and their hashes
