libcamera: Bumped to latest source revision

libcamera uses the host machine python instead of sysroot,
We use the patch file for libcamera source to use the
sysroot python. But libcamera team has fix this issue and,
pushed the changes to libcamera source, now we are pointing
to that particular source revision of libcamera.

In musl, we faced the compilation iisue, so we changed the
source revision pointing to the fix of musl compilation issue.
