cmd/link: assume that runtime.epclntab lives in .text section

Browse source 
Sometimes STEXT symbols point to the first byte of .data
section, instead of the end of .text section. But, while writing
pe symbol table, we should treat them as if they belong to the
.text section. Change pe symbol table records for these symbols.

Fixes #14710
