[Buildroot] [git commit branch/2026.05.x] package/amazon-ecr-credential-helper: needs NPTL

commit: https://gitlab.com/buildroot.org/buildroot/-/commit/4ab4ded4c8a8b07687725df36c89da7daa391693
branch: https://gitlab.com/buildroot.org/buildroot/-/tree/2026.05.x

amazon-ecr-credential-helper calls pthread_getattr_np() which is only
available with NPTL; i.e. always available with glibc (where it
originates from, since 2.2.3), always available with musl (which has
had it since 0.9.10 in 2013), and only available when uClibc has NPTL
(since 1.0.0 in 2015).
