Tests are not platform-agnostic

[calixteman]

Running tests under Windows 10 leads too errors.
In looking quickly at the logs, there is something wrong with eol and paths.
For example:
---- action::tests::test_elf_dbg_stripped stdout ---- thread 'action::tests::test_elf_dbg_stripped' panicked at 'assertion failed: (left == right) left: ["INFO CODE_ID B060AD20C6B47781552708AA192E7739FAC7C84A\r", "FILE 0 /home/calixte/dev/mozilla/dump_syms.calixteman/test_data/linux/basic.cpp\r", "PUBLIC 1000 0 _init\r", "PUBLIC 1020 0 <.plt ELF section in basic.dbg>\r", "PUBLIC 1030 0 <.plt.got ELF section in basic.dbg>\r", "PUBLIC 1040 0 _start\r", "PUBLIC 1070 0 deregister_tm_clones\r"...

right: ["INFO CODE_ID B060AD20C6B47781552708AA192E7739FAC7C84A", "FILE 0 \\home\\calixte\\dev\\mozilla\\dump_syms.calixteman\\test_data\\linux\\basic.cpp", "PUBLIC 1000 0 _init", "PUBLIC 1020 0 <.plt ELF section in basic.dbg>", "PUBLIC 1030 0 <.plt.got ELF section in basic.dbg>", "PUBLIC 1040 0 _start", "PUBLIC 1070 0 deregister_tm_clones"...
