fix(tf-cov-make): fix PLAT_RSS_NOT_SUPPORTED build

Recent changes require an increase in PLAT_ARM_MMAP_ENTRIES for build
[1], but doing so results in an increase in BL2, which cannot be
accommodated within the given SRAM region.

FVP with PLAT_RSS_NOT_SUPPORTED=0 indicates this is an experimental
build to cover code coverage, so the build command [1] has been updated
to remove the SPD build to avoid overflowing of BL2 size.
