pkg/kconfig: accept \n as valid within quoted string
linux-next contains "Kconfig: Add option for asm goto w/ tied outputs to
workaround clang-13 bug", which added this elaborate config variable to
init/Kconfig:
| config CC_HAS_ASM_GOTO_TIED_OUTPUT
| depends on CC_HAS_ASM_GOTO_OUTPUT
| # Detect buggy gcc and clang, fixed in gcc-11 clang-14.
| def_bool $(success,echo 'int foo(int *x) { asm goto (".long (%l[bar]) - .\n": "+m"(*x) ::: bar); return *x; bar: return 0; }' | $CC -x c - -c -o /dev/null)
The current validation in parser.go will complain with "bad quoted
character", because of the '\n' in the quoted string.
Fix it by allowing '\n'.
