[gdb/cli] Don't assert on empty string for core-file
With current gdb we run into:
...
$ gdb -batch '' ''
: No such file or directory.
pathstuff.cc:132: internal-error: \
gdb::unique_xmalloc_ptr<char> gdb_abspath(const char*): \
Assertion `path != NULL && path[0] != '\0'' failed.
...
Fix this by skipping the call to gdb_abspath in core_target_open in the
empty-string case, such that we have instead:
...
$ gdb -batch '' ''
: No such file or directory.
: No such file or directory.
$
...
Tested on x86_64-linux.
