installerfw-sh-functions: add missing newlines

Make sure the /etc/installerfw-environment contains the newline character at
the end. It is reasonable to expect the newline character at the end of text
files.

Additionally, fix code which calculates the lines count. We forgot the newline
character, which will make 'wc -l' return an off-by-one number.
