Absolute paths used as file names in upload

[karrots]

When passing a file to upload as an absolute path instead of just a filename the filename on the ESP module is the full path on local host.

$ nodemcu-uploader upload --compile /path/to/lua/file/mylua.lua
Remove /path/to/lua/file/mylua.lc
file.remove("/path/to/lua/file/mylua.lc")
stdin:1: filename too long
> 
Transfering scwifi.lua as /path/to/lua/file/mylua.lua
Error waiting for esp "recv()
stdin:1: attempt to call global 'recv' (a nil value)
> "
Compile /path/to/lua/file/mylua.lua
node.compile("/path/to/lua/file/mylua.lua")
stdin:1: filename too long
> 
Remove /path/to/lua/file/mylua.lua
file.remove("/path/to/lua/file/mylua.lua")
stdin:1: filename too long

Sometimes it's useful to have the path appended to the filename.
There could be things like...

public/index.html
admin/index.html

There could perhaps be an option to strip some levels of the path from the name, much like you can do with the tar command, but I would not like to use the basename only.

This also affects files specified by current dir prefix: ./file.lua
