main/musl: fixes for using as default libc

- create musl-utils so libc-utils can depend on it
- provide ldd symlink in it also
- provide getent based on uclibc
- cherry-pick NFDBITS patch for sudo

+Subject: [PATCH] add NFDBITS in sys/select.h with appropriate feature tests
+
+the main use for this macro seems to be knowing the correct allocation
+granularity for dynamic-sized fd_set objects. such usage is
+non-conforming and results in undefined behavior, but it is widespread
+in applications.
