ld: pru: Fix resource_table output section alignment

Browse Source 
My commit 261980de18 added alignment for the resource table symbol.
But it is wrong.  The Linux remoteproc driver loads and interprets the
contents of the .resource_table ELF section, not of a table symbol.

Without this patch, if the linker happens to output padding for symbol
alignment, then the resource table contents as viewed by the kernel
loader would "shift" and look corrupted.

ld/ChangeLog:

	* scripttempl/pru.sc  (.resource_table): Align the output
	section, not the first symbol.
