lttng-tools: update to 2.15.0

Remove obsolete patches:
- 010-compat-off64_t-is-not-defined-by-musl.patch: the patched files
  (src/common/compat/compat-fcntl.c and src/common/compat/fcntl.h)
  no longer exist in 2.15.0
- 020-fix-lttng-tools-fails-to-compile-with-libxml2-2-14-0.patch: the
  encode_string() function was refactored in 2.15.0 to use
  xmlCharEncInFunc() instead of handler->input(), so the fix is no
  longer needed

Add musl compatibility fixes in Build/Prepare via sed:
- Remove :: global-namespace qualifier from TFD_CLOEXEC in timerfd.hpp;
  musl defines it as an octal literal so ::TFD_CLOEXEC is invalid C++
- Same fix for EPOLL_CLOEXEC in poller.cpp
- Relax static_assert in consumer.hpp from __cplusplus == 201103L to
  >= 201103L; SDK builds with C++17

Add missing +libstdcpp to DEPENDS (lttng-tools links libstdc++.so.6).

-Subject: [PATCH] compat: off64_t is not defined by musl
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This helps compile with latest musl, where off64_t is not defined unless
-_LARGEFILE64_SOURCE is defined. On glibc, _LARGEFILE64_SOURCE is defined
-if _GNU_SOURCE is defined, so the problem is only seen with musl.
-
-Since the project uses AC_SYS_LARGEFILE, which from the autoconf doc:
-"arrange for 64-bit file offsets, known as large-file support."
-
-As such, it is safe to assume off_t is 64-bit wide. This is checked by a
-static_assert to catch any platform where autoconf would let a 32-bit
-off_t slip.
