[gdb/build,c++17] Fix use of deprecated std::uncaught_exception
When compiling gdb with -std=gnu++17, we run into:
...
../../gdb/inferior.h: In member function ‘void \
infcall_suspend_state_deleter::operator()(infcall_suspend_state*) const’:
../../gdb/inferior.h:83:12: error: ‘bool std::uncaught_exception()’ is \
deprecated [-Werror=deprecated-declarations]
83 | if (!std::uncaught_exception ())
...
Fix this by rewriting using std::uncaught_exceptions.
Tested on x86_64-linux with gcc 9.3.1 and -std=gnu17/gnu++17.
Tested with test-case from RFC patch
https://sourceware.org/pipermail/gdb-patches/2020-June/169970.html.

* inferior.h (struct infcall_suspend_state_deleter): If available, use
std::uncaught_exceptions instead of deprecated
std::uncaught_exception.
