Subject: [PATCH] Tty.xs: Do not mark strlcpy as static

Some libcs e.g. musl do not provide implementation of strlcpy but they
do provide the signature in string.h, if we mark it static here then it
conflicts with the libc define and compiler may warn/error

Fixes
Tty.xs:190:1: error: static declaration of 'strlcpy' follows non-static declaration
strlcpy(                                                                                                                 ^
