  [Driver][RISCV] Fix incorrect compiler-rt path override in BareMetal toolchain after RISCVToolChain removal (#146849)

The RISCVToolChain, which was removed in commit f8cb798,
used a different compiler-rt path relative to the resource-dir
when GCCInstallation was valid. However, this behavior was
unintentionally overridden when it was merged into the
BareMetal toolchain. This patch restores the correct path
handling logic.

After this fix -
With valid GCCInstallation
`<resource-dir>/<llvm-rel-ver>/lib/<target-triple>libclang_rt.builtins.a`

Without valid GCCInstallation
`<resource-dir>/<llvm-rel-ver>/lib/baremetal/libclang_rt.builtins-<target>.a`
