libsimplelog: upgrade 1.0.8 -> 1.1.0

Upgrade libsimplelog to the latest upstream version 1.1.0.

Drop 0001-allow-build-with-cmake-4.patch as it is now integrated
upstream (commit 4827c4325063266f6d2a7e133a9d3a9050ff6a3c).

Update LIC_FILES_CHKSUM due to upstream updating the copyright year 
range from 2024 to 2024-2026 in LICENSE.txt. The project remains fully 
under the MIT license.

Append -D__LINUX__=1 and -D_GNU_SOURCE=1 to EXTRA_OECMAKE to enable 
Linux and GNU-specific extensions like sched_getcpu() for better 
performance effectiveness. These flags are optional; without them, 
version 1.1.0 remains fully backward compatible and adapts perfectly 
with strictly POSIX musl environments.
