Fix PR gdb/17917 Lookup build-id in remote binaries
GDB doesn't support loading debug files using build-id from remote
target filesystems.
This is the case when gdbserver attached to a process and a gdb target
remote occurs over tcp.
With this change we make build-id lookups possible:
(gdb) show debug-file-directory
The directory where separate debug symbols are searched for is "/usr/local/lib/debug".
(gdb) set debug-file-directory /usr/lib/debug
(gdb) show sysroot
The current system root is "target:".
(gdb) target extended-remote :46615
Remote debugging using :46615

Try: dnf --enablerepo='*debug*' install /usr/lib/debug/.build-id/6e/0a874dca5a7ff831396ddc0785d939a192efe3.debug
(No debugging symbols found in target:/usr/sbin/mariadbd)
Observe it didn't look for
/usr/lib/debug/.build-id/6e/0a874dca5a7ff831396ddc0785d939a192efe3.debug
on the remote target (where it is) and expected them to be installed
locally.
As a minor optimization, this also changes the build-id lookup such that
if sysroot is empty, no second lookup of the same location is performed.
