package/libfuse3: fix build failure on Microblaze due to wrong symver attribute detection

Add a patch to fix symver wrong detection. As explained into the patch
pending upstream[1] __has attribute() gives false positive when an
attribute is not supported[2] and this leads to assuming symver attribute
is present but it's not. This consequentely leads to build failure. I.e.
Microblaze doesn't really support it since it doesn't include elfos.h in
config.gcc that determines symver to be available.
