[RFC PATCH 01/11] sysctl: make some functions unstatic to access by arch/lib

[Hajime Tazaki <tazaki@xxxxxxxxxxxxxx>]

libos (arch/lib) emulates a sysctl-like interface by a function call of
userspace by enumerating sysctl tree from sysctl_table_root. It requires
to be publicly accessible to this symbol and related functions.
