MIPS: move _stext definition to vmlinux.lds.S

The _stext symbol is intended to reference the start of the text section.
However, it currently relies on a fragile link order because the existing
EXPORT(_stext) resides within the .text section, which is not guaranteed
to be placed first.

Move the _stext definition to the linker script to enforce an explicit
ordering.
