qemu-check.exp: match core assert/panic strings on a single line

The regular expression used to detect TEE core panics or assertion
failures must not allow multi-line text to match, otherwise the following
input may trigger it (test case: xtest 1007 with "make COMPILER=clang").

E/TC:? 0 TA panicked with code 0xbeef

E/LD:  assertion 'maps[map_idx].sz == sz' failed at ldelf/ta_elf.c:1451 in ta_elf_print_mappings()

In addition to using '[^n]*' instead of '.*', a couple of things need
fixing too:

- In Expect, `^` and `$` are the beginning and end of the current matching
buffer, not the beginning and end of a line. Therefore `^` is not
appropriate here.
- `\n` should not be matched because if it is consumed for example at the
end of an expression to mean "end of line", then it cannot be available to
another expression to mean "beginning of line".
