cmd/link/internal/ld: remove unused call to os.Getwd

This call to os.Getwd (or getwd) has been part of the linker since the C
implementation in 7d507dc6e6. It stopped being used in 26438d4d80, and
survived the conversion to Go in 1f9dbb60ef.

Its return value goes unused (the linker gets the value for AT_comp_dir in
dwarf.go), remove it.
