[Fix] nvm_resolve_local_alias: avoid using variable as printf format string

Browse Source 
Using a variable as the format string means `%` characters in alias names would be interpreted as format specifiers.
Use `%b` format with the variable as an argument to safely interpret `\n` escapes.

Bug introduced in 9b91734f0b.
