community/tlp: upgrade to 1.3.0
A couple of breaking change: New configuration scheme
/etc/default/tlp is replaced by /etc/tlp.conf
Settings are read in the following order:
1. Intrinsic defaults
2. /etc/tlp.d/*.conf - Drop-in customization snippets
3. /etc/tlp.conf - User configuration
In case of identical parameters, the last occurence has precedence
Parse config files instead of sourcing --> no more shell expansion
