thermald: use unversioned libchrome libraray.

Libchrome is changing pkg-config and .so library name from
xxxx-${libbase_ver}.{pc,so} to xxx.{pc,so}.

Libchrome uprev rebuild will be handled by ebuild subslot change. And
there's no need to install multiple libchrome. Keeping libbase_ver
suffix will cause troubles on linking libraries when developers wants to
test locally emerge a-single-package without build_packages, after a
libchrome uprev. Especially in a case a package depends on another
package(library), and both depends on libchrome. Thus, removing
libbase_ver from suffix.
