[COFF] Don't mark mingw .eh_frame sections writable
This improves compatibility with GCC produced object files, where
the .eh_frame sections are read only. With mixed flags for the
involved .eh_frame sections, LLD creates two separate .eh_frame
sections in the output binary, one for each flag combination,
while ld.bfd probably merges them.
The previous setup of flags can be traced back to SVN r79346.
