support/scripts/gen-bootlin-toolchains: improve dependencies of ARM toolchains

The current description of the Bootlin ARM toolchains allows them to
be selected for ARM big endian configurations, which obviously doesn't
work as these Bootlin ARM toolchains are little endian only.

We fix this by adding BR2_arm in the list of conditions for those
toolchains.

Will allow to fix:
