package/gdb: handle lzma option for host-gdb

Browse Source 
For target gdb, we properly enable/disable lzma support depending on
BR2_PACKAGE_XZ.

However, for host-gdb we don't do anything, which can lead the gdb
configure script to detect and use a system-provided xz library, which
is not desired.

Instead, add an explicit option BR2_PACKAGE_HOST_GDB_LZMA, which when
enabled pulls in host-xz, but also when disabled ensures gdb doesn't
try to use a system-provided xz library.
