[LOAD][UNLOAD] Fix w*printf() format strings (#3319)

Also:
    - Set ServiceName.MaximumLength.
    - Fix MSVC warnings:
    '...\load\load.c(19): warning C4267: '=': conversion from 'size_t' to 'USHORT', possible loss of data
    '...\unload\unload.c(19): warning C4267: '=': conversion from 'size_t' to 'USHORT', possible loss of data'
    '...\unload\unload.c(24): warning C4476: 'wprintf' : unknown type field character 'U' in format specifier'
    '...\unload\unload.c(24): warning C4474: 'wprintf' : too many arguments passed for format string'
