tools lib traceevent: Remove libtraceevent

libtraceevent is now out-of-date and it is better to depend on the
system version. Remove this code that is no longer depended upon by
any builds.

Committer notes:

Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so
that 'make perf-tar-src-pkg' works.

-DESCRIPTION
------------
-Trace sequences are used to allow a function to call several other functions
-to create a string of data to use.
-
-The _trace_seq_init()_ function initializes the trace sequence _s_.
-
-The _trace_seq_destroy()_ function destroys the trace sequence _s_ and frees
-all its resources that it had used.
-
-The _trace_seq_reset()_ function re-initializes the trace sequence _s_. All
-characters already written in _s_ will be deleted.
-
-The _trace_seq_terminate()_ function terminates the trace sequence _s_. It puts
-the null character pass:['\0'] at the end of the buffer.
-
-The _trace_seq_putc()_ function puts a single character _c_ in the trace
-sequence _s_.
-
-The _trace_seq_puts()_ function puts a NULL terminated string _str_ in the
-trace sequence _s_.
-
-The _trace_seq_printf()_ function puts a formated string _fmt _with
-variable arguments _..._ in the trace sequence _s_.
-
-The _trace_seq_vprintf()_ function puts a formated string _fmt _with
-list of arguments _args_ in the trace sequence _s_.
-
-The _trace_seq_do_printf()_ function prints the buffer of trace sequence _s_ to
-the standard output stdout.
-
-The _trace_seq_do_fprintf()_ function prints the buffer of trace sequence _s_
-to the given file _fp_.
-
-RETURN VALUE
-------------
-Both _trace_seq_putc()_ and _trace_seq_puts()_ functions return the number of
-characters put in the trace sequence, or 0 in case of an error
-
-Both _trace_seq_printf()_ and _trace_seq_vprintf()_ functions return 0 if the
-trace oversizes the buffer's free space, the number of characters printed, or
-a negative value in case of an error.
-
-Both _trace_seq_do_printf()_ and _trace_seq_do_fprintf()_ functions return the
-number of printed characters, or -1 in case of an error.
