test/boot: Make BOOTSTD tests depend on UT_BOOTSTD
While we have a symbol for controlling if we will be testing BOOTSTD or

bootstage: Fix out-of-bounds read in reloc_bootstage()
bootstage_get_size() returns the total size of the data structure
including associated records.
When copying from gd->bootstage, only the allocation size of gd->bootstage
must be used. Otherwise too much memory is copied.
This bug caused no harm so far because gd->new_bootstage is always
large enough and reading beyond the allocation length of gd->bootstage
caused no problem due to the U-Boot memory layout.
Fix by using the correct size and perform the initial copy directly
in bootstage_relocate() to have the whole relocation process in the
same function.
