confusing deprecation messaging

[IanButterworth]

The depwarn created here creates a log message with a malformed location

JLLWrappers.jl/src/products/executable_generators.jl

Line 20 in a1025a8

Base.depwarn(string($(product_name), "() is deprecated, use the non-do-block form"), $(string(product_name)))

┌ Warning: ffmpeg() is deprecated, use the non-do-block form
│   caller = ip:0x0
└ @ Core :-1

Also, perhaps the message should say Warning: using executables via a function return like ffmpeg() is deprecated by JLLWrappers, use the non-do-block form

Even with --depwarn=error it appears to be coming from FFMPEG_jll but the src is JLLWrappers
