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.
