s390: unify linker symbols usage
Common code defines linker symbols which denote sections start/end in
a form of char []. Referencing those symbols as _symbol or &_symbol
yields the same result, but "_symbol" form is more widespread across
newly written code. Convert s390 specific code to this style.
Also removes unused _text symbol definition in boot/compressed/misc.c.
