The read() function expects a pointer to buffer, not address of
pointer. Three instances were incorrectly passing &buffer instead
of buffer to read().

Latest musl has removed the declaration from string.h [1] as it only
implements POSIX version alone and string.h in glibc implements GNU
version of basename. This now results in compile errors on musl.
This might be a warning with older compilers but it is error with
Clang-17+ as it treats -Wimplicit-function-declaration as error
Switch the use in backlight_init function to use POSIX version

In 913d7c15f7 stricter error checking was
introduced to the strtol call, which broke reading backlight values.
Since every sysfs backlight file ends with a newline.
As noted in a comment in the previous MR to prevent damaged pointers
after calling asprintf, replace every asprintf call with str_printf.

Move the DRM-backend into a new sub-directory to make it stand out from
libweston core. This facilitates splitting drm.c into more files later.
vaapi-recorder is used only by DRM-backend, move that too.
libbacklight is used only by DRM-backend and a manual test program, and is
moved as well.
