c++/modules: Fallback to ftruncate if posix_fallocate fails [PR115008]
Depending on the libc and filesystem, in cases where posix_fallocate
cannot do an efficient preallocation it may return EINVAL. In such a
case we should fall back to ftruncate instead.
Apparently, depending on the system the use of posix_fallocate can have
a noticeable speedup over ftruncate in general (depending on the system)
so it probably isn't worth it to use ftruncate in all cases.

* module.cc (elf_out::create_mapping): Fallback to ftruncate if
posix_fallocate fails.
