lttng-tools: bump to version 2.8.2

The current patches are dropped because they were merged upstream.

The new patches exist to fix the build with musl. They were submitted on
the lttng-dev mailing list, but not merged yet, or not merged in 2.8.2.

LTTng-tools now has its man pages written in AsciiDoc and they get
converted to troff at build time. This is not needed in a Buildroot
image anyway.

The --enable-lttng-ust/--disable-lttng-ust configure options are renamed
to --with-lttng-ust/--without-lttng-ust in v2.8.

Subject: [PATCH] Fix: build failure when __GLIBC_PREREQ is missing
The musl C library does not provide the __GLIBC_PREREQ macro. Instead of
relying on glibc version test, check directly for the availability of
epoll_create1().

Some implementations of strtol() like the one in musl will
return EINVAL in perror when no valid number was found in
the string.
