readelf/objdump: Display SFrame fixed RA offset as 'f' in dump

For the SFrame FRE frame-pointer (FP) offset from CFA a 'u' is displayed
if it is unavailable.

For the SFrame FRE return-address (RA) offset from CFA a 'u' was
displayed if the ABI uses a fixed RA offset from CFA. By chance a
'u' was also displayed if the RA offset is unavailable, as the string
buffer was not initialized after formatting the FP offset. Note that it
could not occur that the FP offset was erroneously displayed as RA
offset, as the SFrame format cannot have a FRE with FP offset without
RA offset.

For the FRE RA offset display 'f' if the ABI uses a fixed RA offset
from CFA. Display a 'u' if it is unavailable.
