package/lm-sensors: always pass TARGET_CONFIGURE_OPTS

package/lm-sensors: always pass TARGET_CONFIGURE_OPTS

lm-sensors dropped MACHINE variable since version 3.6.0 and
https://github.com/lm-sensors/lm-sensors/commit/0863eff8fa1d32797e3aec19672878aff893b0ae
instead it uses $(CC) -dumpmachine to guess the architecture

However, as $(TARGET_CONFIGURE_OPTS) is only passed to build step and
not to install steps, this result in some binaries being built for the
host during install step and raising a build failure on some autobuilders
