perf callchains: Disable unwind libraries when libelf isn't found
I.e. do the same as when NO_LIBELF is explicitely passed in the 'make'
command line, fixing this:
Auto-detecting system features:
... dwarf: [ OFF ]
... glibc: [ on ]
... gtk2: [ OFF ]
... libaudit: [ OFF ]
... libbfd: [ OFF ]
... libelf: [ OFF ]
... libunwind: [ OFF ]
... libdw-dwarf-unwind: [ OFF ]
... DWARF post unwind library: libdw
