Ovidiu Panait d2bb23badf tests: add testcase for alignment issues with contiguous note sections
Add a testcase for the following reported alignment issue with contiguous note
sections (#275):

"""
If a binary has multiple SHT_NOTE sections and corresponding PT_NOTE
headers, we can see the error:

patchelf: cannot normalize PT_NOTE segment: non-contiguous SHT_NOTE sections

if the SHT_NOTE sections aren't sized to end on aligned boundaries. An example
would be a binary with:

[ 2] .note.ABI-tag NOTE 00000000000002f4 000002f4
0000000000000020 0000000000000000 A 0 0 4
[ 3] .note.gnu.propert NOTE 0000000000000318 00000318
0000000000000030 0000000000000000 A 0 0 8
[ 4] .note.gnu.build-i NOTE 0000000000000348 00000348
0000000000000024 0000000000000000 A 0 0 4

NOTE 0x0000000000000318 0x0000000000000318 0x0000000000000318
0x0000000000000030 0x0000000000000030 R 0x8
NOTE 0x00000000000002f4 0x00000000000002f4 0x00000000000002f4
0x0000000000000078 0x0000000000000074 R 0x4

since the PT_NOTE section at 2f4 covers [2] and [3] but the code
calclates curr_off should be 314, not the 318 in the binary. This
is an alignment issue.
