libgluonutil

The import of libgen.h required for basename() was missing. This lead to
undesired behavior on 64 bit systems, where only the upper 32-bit of the
returned pointer was used.

On ARM64 systems such as mediatek-filogic, this lead to a signed extend
of the 32-bit address, leading to a crash of respondd.
