[Buildroot] [PATCH 1/1] boot/opensbi: fix build with empty OPENSBI_PLAT

[Fabrice Fontaine]

Fix the following build failure when OPENSBI_PLAT is empty raised since
commit 9b5b7165deb91bad3cdb1ea0dd8f940eff75f3a9:

/usr/bin/install -m 0644 -D /nvmedata/autobuild/instance-4/output-1/build/opensbi-0.9/build/platform//firmware/fw_jump.bin /nvmedata/autobuild/instance-4/output-1/images/fw_jump.bin
/usr/bin/install: cannot stat '/nvmedata/autobuild/instance-4/output-1/build/opensbi-0.9/build/platform//firmware/fw_jump.bin': No such file or directory

Fixes:
