Slightly tweak error when unable to bind port

A slight improvement over 2d2d8fae3d8bc4e82dc631d93c6e19f954bbee04 -- we don't know that it's the daemon, it could be the GUI.

[Qt] Fix enable/disable show and remove buttons
Remove stale and redundant src/.gitignore file

This commit removes completely the src/.gitignore file, given that the
precedent for ignoring artifacts within the `src` directory is to
add entries for them to the root .gitignore file.

Note also that the lone entry in src/.gitignore is stale anyway. As of
the switch to Autotools in 35b8af9, the build no longer build creates
artifacts in `src/test_bitcoin`. They are now written to
`src/test/test_bitcoin`, and this latter path is already ignored in the
root .gitignore file.
