package/libfuse3: fix build failure with no NPTL

Since the bump of libfuse3 from 3.16.2 to 3.17.1 in Buildroot commit
a4430578aeb6ca460813f4ff7d833cdd839a3249, libfuse3 uses
pthread_setname_np() which is only available with NPTL.

Some initial fixes were made upstream, but are insufficient to fully
fix the problem, so this commit brings additional upstream patches
fixing the issue completely.

Fixes:

+Subject: [PATCH] Fix meson function tests
+
+Several meson tests were incorrectly failing
+
+Checking for function "static_assert" : NO (cached)
+Checking for function "pthread_setname_np" : NO (cached)
+Check usable header "#include <linux/close_range.h>" : NO (cached)
+
+These functions get now tested with compilation tests
+and get found on my system.
+
+Checking if "static_assert check" compiles: YES
+Checking if "pthread_setname_np check" compiles: YES
+Checking if "close_range check" compiles: YES

+Subject: [PATCH] meson.build: make special_funcs check more reliable
+
+Unfortunately while cross-compiling with build tools like Buildroot it
+happens to have repeated flags or anything that could lead to a warning.
+This way the check fails because of a warning not related to the special
+function. So let's use cc.links() and increase minimum meson_version to
+0.60 since cc.links() has been added during that version.
