gdbserver: fix Makefile dependency of regformat-generated files on regdat.sh
The intent of the rules modified by this patch is that the *-generated.c
files generated by regdat.sh are re-generated in the event that
regdat.sh is modified. However, if I build, touch regdat.sh, and build
again, the files are not re-generated during the second build.
This is because regdat.sh is specified as an order-only dependency [1],
after the pipe. Make therefore only ensures that regdat.sh exists
before generating the target file, it doesn't check the timestamp of
regdat.sh.
This patch changes it to be a regular prerequisite.
The rules use the $< variable, which is substituted by the first
prerequisite only, so the command lines won't change.

gdb/gdbserver/ChangeLog:
* Makefile.in (%-generated.c): Make $(regdat_sh) a regular
prerequisite.
