Subject: [PATCH] Robuster string parsing in bash script

In the `avrdude` call the elf-file input argument is used:
"... -Uflash:w:$1:e".
On some systems the "$1:e" is interpreted as the extension of this
argument, i.e. only producing "elf" instead of the full
"<path-to_elf.elf>"

Adding curly braces "${1]:e" ensures robust parsing.
