signal.7: Better description for SIGFPE

SIGFPE has comment "Floating-point exception", which corresponds to
the FPE acronym.  But this is misleading as this signal may also be
generated by an integer division by 0.

Change it to "Erroneous arithmetic operation" from POSIX.
Note: the GNU C Library manual says "fatal arithmetic error".
