package/nfs-utils: bump version to 2.6.2

nfs-utils 2.6.2 adds nfsrahead tool to set readahead through sysfs, but
this tool is mandatory and requires libmount that in order requires
libblkid. Also we need a local patch that is already pending upstream to
avoid failing static linking:
https://patchwork.kernel.org/project/linux-nfs/patch/20220809223308.1421081-1-giulio.benetti@benettiengineering.com/

So let's select:
- BR2_PACKAGE_UTIL_LINUX_LIBMOUNT
- BR2_PACKAGE_UTIL_LINUX_LIBBLKID
and add the pending patch for fixing static linking failure due to wrong
order of libraries in linker list(-lblkid must follow -lmount). This is
achieved by using pkg-config that is already a dependency of this package.

+
+-lmount must preceed -lblkid and to obtain this let's add:
+`pkg-config --libs mount`
+in place of:
+`-lmount`
+This ways the library order will always be correct.
