Update rockboxdev.sh:

- Change alsa-lib and libffi source to use https instead of ftp
- Change glib source to current path (avoids redirect)
- Change mpc source to GNU mirror because www.multiprecision.org seems down
- Change remaining http to https

Original reason for the change is that on WSL2 (Windows 11) for some reason ftp links do not appear to work.
