[packages] tmux: fix b64_ntop conflict

Certain uClibc versions declare b64_ntop but do not actually implement it, this leads to conflicting declarations
when the tmux compat replacement function is used. Rename the replacement to local_b64_ntop and define b64_ntop
to local_b64_ntop if the libc indeed implements it.
