i386: Fix up x86_function_profiler -masm=intel support [PR114094]

In my r14-8214 changes I apparently forgot one \n at the end of an instruction.
The corresponding AT&T line looks like:
"1:\tcall\t*%s@GOTPCREL(%%rip)\n"
but the Intel variant was
"1:\tcall\t[QWORD PTR %s@GOTPCREL[rip]]"

Fixed thusly.
