cdf-copy.cc doesn't compile on Solaris:

copybook_elem_t::open_file(const char*, bool)’:

GLOB_BRACE and GLOB_TILDE are BSD extensions not in POSIX.1, thus
missing on Solaris probably due to its System V heritage.

This patch introduces fallback definitions to avoid this.

Bootstrapped without regressions on amd64-pc-solaris2.11,
sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu.
