Disable progress bar on dumb terminals by default 

The progress bar requires the terminal emulator to support ANSI escape
sequences. Normally, TERM is set to dumb to indicate that the terminal
emulator doesn't support any ANSI escape sequences. Attempting to use
ANSI escape sequences on dumb terminals will lead to weird output. In
order to make apk work by default, even on dumb terminals, this commit
introduces an additional check which consults $TERM and disables the
progress bar if it is set to "dumb".
