Ian Rogers 3f1800cade bpftool: Align output skeleton ELF code
[ Upstream commit 23671f4dfd ]

libbpf accesses the ELF data requiring at least 8 byte alignment,
however, the data is generated into a C string that doesn't guarantee
alignment. Fix this by assigning to an aligned char array. Use sizeof
on the array, less one for the \0 terminator, rather than generating a
constant.

Fixes: a6cc6b34b9 ("bpftool: Provide a helper method for accessing skeleton's embedded ELF data")
