libxcrypt: import from packages feed

Import libxcrypt from the packages feed to the main OpenWrt repo,
as glibc 2.41 doesn't provide libcrypt (since 2.39 release).

+define Package/libxcrypt/description
+  libxcrypt is a modern library for one-way hashing of passwords. It supports
+  a wide variety of both modern and historical hashing methods: yescrypt,
+  gost-yescrypt, scrypt, bcrypt, sha512crypt, sha256crypt, md5crypt, SunMD5,
+  sha1crypt, NT, bsdicrypt, bigcrypt, and descrypt. It provides the traditional
+  Unix crypt and crypt_r interfaces, as well as a set of extended interfaces
+  pioneered by Openwall Linux, crypt_rn, crypt_ra, crypt_gensalt,
+  crypt_gensalt_rn, and crypt_gensalt_ra.
