[PATCH v2] tools: lib: thermal: Correct CFLAGS and LDFLAGS in pkg-config template

[Romain Gantois]

There are two issues with the current pkg-config template.

Firstly, the -lthermal linker flag is missing.

Secondly, the libnl3 include directory compiler flag references "include"
instead of "includedir", which leads to an unexpanded variable when
pkg-config is called. Moreover, it isn't necessary to add this flag here,
since the "Requires" field will cause pkg-config do add it automatically.
The same logic applies to the LDFLAGS for libnl3.

Add the missing -lthermal flag and remove unnecessary and incorrect libnl3
flags.
